Introduction
The measurement with CAT1000S can be realized in two ways:
‰
Start GEOPAK and call the surface measurement.
‰
Start CAT1000S and activate GEOPAK for the real measurement.
In some instances, the procedures are a bit different for the two types of measurement.
We will indicate this wherever applicable.
Getting Started and Further Steps
If you did not yet load a model, you first should do that (see details of "Load Model ").
You can ...
€
View the model and get information about it (see details of "View and
Analyse Model ")
€
Select single surfaces and slightly modify the model (see details of "Extract
CAD-Data ")
€
Search points on the borders of the model and send these to GEOPAK for
further processing (see details of "Search Border Points ")
€
Create sections through the model (see details of "Presetting for Definition of
Sections").
€
Configure your screen (see details of "Screen Configuration ")
€
Align the part (see details of "Define Co-ordinate System ")
€
Perform the actual comparison with the measured points (see details
"Comparison with Measurement Data ")
€
Turn and rotate the points so that the deviations as a whole get minimised
(see details of "Best Fit ")
€
Prepare graphical and numerical documentation of the results (see
"Presentation of Results ")
€
Send the results in standard formats to other systems (see details of "Output
to External Systems ")
€
Measure more parts in repeat mode (see details of "Repeat Mode ")
4.2
Screen Configuration
This topic is relevant to CAT1000S only
CAT1000S offers several possibilities in order to inform you about the existing data. All
information windows are interrelated. This means: All information windows are always
updated simultaneously. For example, a point that you delete in the main window is
immediately removed from the "List of Measurement Points", and the histograms as well
as the information window are also recalculated without this point.
Usually, the drawing of the model takes most of the screen. Besides this information there
are
€
The "List of Measurement Points" containing the numerical values
€
A histogram with information window (explanation of the colours)
€
the Result Window .
10
v 3.0
24.05.06
Main Window
If you have chosen your favourite window arrangement and sizes, you can store this; then
you get the same configuration again when restarting the program. You store the
configuration via the pull-down menu ("Window / Store Window Positions").
Histogram (Information Window)
The classes of the histogram are labelled in a different way, depending on whether all
measurement points have the same tolerance or not.
If all measurement points have the same tolerance, the classes (limits) are labelled in
millimetres.
If there are measurement points with different tolerances, the classes are labelled in
"Percent", and the points are assigned to these classes depending on the percentage of
the individual tolerance.
List of Measurement Points
In this list, you automatically find all necessary information about the measurement points.
The table is online-updated line by line during the measurement course.
4.3
Toolbar Configuration
In CAT1000S / CAT1000P you can customize each toolbar. Proceed as follows:
Ö
Click with the right mouse button on the relevant toolbar.
Ö
In the subsequent dialogue "Adjust toolbar", you can add or remove the
desired buttons. Furthermore, you can change the sequence of the shown
icons and insert separators.
If you activate the button "Reset", the toolbar is reset to the way it was before starting the
dialogue "Adjust toolbar".
Tip:
You can arrange toolbars with drag-and-drop either horizontally or vertically.
4.4
Window Positions
You can select between two modes of window style, namely the
‰
normal mode and the
‰
“Split Screen” mode.
Hint:
In the default, the windows are displayed in the normal mode.
If you activate the "Split Screen" function in the pull-down menu, all windows are
displayed in the "Split Screen" mode.
The "s" accelerator button offers another possibility: You can switch between the
normal mode and the “Split Screen” mode.
You get the functions via the menu bar and “Window". The store, load and default
functions are valid for the normal mode as well as for the “Split Screen” mode.
"Split Screen" mode.
By the "Split Screen" function, it is possible to display at the same time e.g. windows of
CAT1000S and GEOPAK or CAT1000P and GEOPAK on your screen.
24.05.06
v.3.0

Main Window
Camera Position of the other Mode
In CAT1000S, you dispose of the additional "Camera Position of the other Mode" function.
This function offers the possibility to transfer the stored display parameters (e.g.: angle
(after rotation of the model), zoom factor and display positions of the CAD model on the
screen) between the “Split Screen” mode and the normal mode.
Storage
You can store those window positions you have selected at last according to your ideas.
At restart, you will get these positions again.
Restore
Via this function, you can restore the status of your last defaults you have stored.
Default
Under "Default Window Positions", you will find a configuration that Mitutoyo considered to
be useful. Wherever your window positions may be, via this function you return into a
home position, with which you can, in each case, continue your work.
4.5
Create a New Part
Change to the PartManager. There, you proceed as described in Create a New Part in the
PartManager documentation.
4.6
New Model
To get to the function "New model", go to the menu "File" in CAT1000S.
Task
With this function, an empty template is opened. Afterwards you can, for example, import
a new model.
4.7
Open Model
To get to the function "Open model", go to the menu "File" in CAT1000S.
Task
When you open a model, you can only view but not measure this model.
4.8
Close Model
To get to the function "Close model", go to the menu "File" in CAT1000S.
Task
The 3D-view of the current model is closed. By that, the part is released again by
CAT1000S in the PartManager.
Now, the part is no longer available for measurement tasks.
4.9
Clear Model
To get to the function "Clear model", go to the menu "File" in CAT1000S.

Main Window
Example:
€
€
€
You are working with a CAD model in CAT1000S. You have, for example,
already saved several views of the model.
You want to load a new, current model. The new model hardly differs from
the old model.
Use the function "Clear model". Then import the updated model. The new
model is loaded in the same part.
If you have deleted the old model, you should not close CAT1000S. If you close
CAT1000S before you have loaded the new model, all CAT1000S files for this
part are deleted.
4.10
Load Model
4.10.1
Load Model
Prerequisite
The program CAT1000S creates tolerance comparisons between 3D-surfaces and
measurement points.
For the import of CAD-files, interfaces are used.
CAT1000S and CAT1000P work with CAD-files (planes and complete models). These
CAD-files must have been created with a CAD-system. CAT1000S / CAT1000P supports
the following formats:
‰
IGES
‰
CATIA V4
‰
CATIA V5
‰
CATIA V5 RepairConverter
‰
Parasolid
‰
Pro/E
‰
STEP
‰
VDAFS
‰
Unigraphics
‰
SolidWorks
The import of VDAFS-, IGES- and SAT-formats is installed as a standard. The remaining
standards are installed on order.
Read the topic
Dialogue "Load Model".
4.10.2
Dialogue "Load model"
Start
To get to the dialogue “Load modal” use the menu “File” / “Import single model” or “Import
multiple model”.
24.05.06
v.3.0

Main Window
For using a feature file, read the help topics for the topic "WEPROM". Start with the topic
"Import of CAD-Files with Feature File: Introduction".
CAT1000S / CAT1000P requires planes. Are there no planes, no model is displayed.
Although some CAD-systems display all kinds of lines, those are not sufficient for a
spacial comparison. The lines must be connected with the planes.
In case that the plane to be measured does not fully correspond to the specimen,
CAT1000S / CAT1000P offers a variety of options to adjust the default values according
to the specimen.
4.10.2.1
Options in the Dialogue "Load CAD-Model"
Mirror
€
Settings
€
€
You can mirror the model using the symbols
,
and
for
"No mirroring". These options are important for the automotive industry. The
engineering data are, e.g. for a wing, only drawn up once, e.g. for the right
wing. However, both the right and the left wing must be measured.
The following paragraph is only relevant to CAT1000S (topic: sheet
thickness, see below).
For sheet panel parts you can enter a "sheet thickness". For panel sheets
sometimes only the form of the "underside" is given, but probing is only
possible on the "upside". In this case you enter the sheet thickness which is
then compensated for in the course of the tolerance comparisons.
Furthermore it is possible
€
that although the upside of a sheet panel part is defined by the CAD data,
€
the press tool of the underside must be measured.
Ö
In this case you enter the sheet thickness and
Ö
click on the appropriate checkmark button.
€
This appears as though you had entered a (not permitted) negative sheet
thickness.
€
You can assign the characteristic "Fixture" to the complete CAD-Model. For
this, refer to the topic "Fixtures: Introduction".
Often the CAD data are faulty. We can help you with some
problems (for this, please read thoroughly under the topic "Extract
CAD data"). In case of other problems, the data record needs to
be revised.
Automatic monitoring
Upon each restart, CAT1000S / CAT1000P checks if the latest CAD data of the work
piece to be measured are installed. If not, an alert message appears
•
that the data have changed and
•
a message to load the changed data to avoid mistakes.

Load Model: Steps
Three possibilities
There are three possibilities to load a model.
€
Via the menu "File" / function "Open model”.
Please note:
You can use the function “Open model” only for viewing the model. If you
want to work with the model, you need to import it (see below).
€
Via the menu "File" / function "Import single model".
€
Via the menu "File" / function "Import multiple model".
Import single model
In the dialogue window "Import single model", use the button to select the required
model from a directory.
€
The list box "CAD format" shows the file format of the selected CAD model.
€
However, it is possible that the file extension has been defined by the user.
Ö
In this case, use the list box to assign the required CAD file format to the
CAD file.
€
The list box only displays those CAD file formats that are released by the
dongle.
In the dialogue windows "Import single model” and “Import multiple model” you find the
button “Import settings”.
Activate the button “Import settings” in order to determine the settings of the translator of
the selected file type in the following dialogue.
For more information about this topic, please refer to "Load Model: Import Settings".

View and Analyse Model
Model View
Once the model has been loaded, you
can view it from all sides. In the icon bars and toolbars, CAT1000S offers a series of
functions (see picture above) with which you can e.g.
€
view the model in the different co-ordinate planes and
€
rotate it around the single axes.
It is possible to view the model
€
with a shading or only view the
€
edges of the model (polygon drafts).
€
you can also display the surfaces by aid of a cloud of points or if you prefer
€
a wire-frame model. In this model, all edges that you cannot see are
calculated.
See further details of topic "Windows and Measurement Points".
4.12
Windows and Measurement Points
Any time you want, it is possible to open an additional window via the "Window / New
Window" pull-down menu. In any case, you can zoom or rotate in the windows
independently from the others.
If new data (e.g. measurement points) are added, all open windows are automatically
updated.
€
The following section is only of relevance for CAT1000S (Topic: Size of
spheres).
€
Measurement points are drawn as small spheres. If you want to change the
size of these represented spheres, you select in the "Settings" pull-down
menu the "Graphics / General Settings" functions. There, you can determine

Rotate View
If you want to measure a part with CAT1000S, you can see the part in the
CAT1000S main window in a centered position; the Z-axis is upright to the screen.
Normally, you would like to display your part on the screen in the same angle of view it is
positioned on the CMM. That means, you must rotate the part around one or several axes.
You can do that ...
‰
...e.g. with the X, Y and Z keys on your keyboard (with the shift button, you
rotate in the opposite direction) or …
‰
‰
with the icons (here an example for "Rotate +Z"). If you point your
mouse cursor on one of the symbols, the balloon shows which rotation
function you have activated (we explain projections later).
Furthermore, you have the possibility to rotate the model with the arrow keys
and the PgUp key respectively the PgDn key. Rotation is realised around the

With the commands window the program provides you with an instrument to have all
commands displayed. These include, for example, the following commands:
€
Element begin
€
Element end
€
Single measurement points
€
Commands for CMM movement
€

Below this line you find the three buttons "Stop", "Continue" and "Delete" (from left).
In the View you see the commands in a tree structure.
Overview
You can control,
€
which commands / elements have already been transferred to GEOPAK and
have already been measured.
The list displays these completed commands in bold;
€
which commands / elements are still in the buffer (normal fond) and which
commands still need to be worked off;
€
which command in the list is currently being processed.
The window "Commands window" does not replace the result field in GEOPAK
with its detailed information.

Commands Window and Buffer
The commands window is linked with a buffer. In this buffer, all data are stored that are
displayed in the commands window.
€
Thanks to the buffer you will, in case of a collision, not loose all the data that
were previously sent by CAT1000S / CAT1000P to GEOPAK.
For how to avoid collisions, refer to "Collision Control in CAT1000S /
CAT1000P".
€
Furthermore, this buffer ensures that you do not loose data from the
GEOPAK buffer.
€
The buffer simplifies working with the program. You need not wait until a
measurement of an element or a point is completed, before you can start the
next measurement.
For further information about this topic, refer to
Application Example for the Commands Window

Commands in the Buffer
All commands are temporarily saved in a buffer. These include, for example, the following
commands:
€
Element begin
€
Element end
€
Single measurement points
€
Commands for CMM movement
€
Clearance height
€
Commands for the automatic element measurement
An element is only displayed in the 3D-view after its successful completion.

Avoidance Path
Settings for measurement: General
Here you can establish a permissible deviation. This function is necessary because
CAT1000S / CAT1000P expects an ideal element for the calculation of the probing points.
It may, however, happen that elements in the CAD model slightly deviate due to roundoff
errors. Verification of these probing points may show that these points are not located
exactly on the element. As a result of such check, the probing points would be regarded
as not valid points.
Establishing a permissible deviation helps overcome this problem. This distance defines
how far the calculated probing points are allowed to deviate from the ideal element. Within
this deviation, the probing points are regarded as valid probing points.
If the permissible deviation is a small value, surfaces will be searched for in a
small range around the calculated measurement point.
The smaller the range the faster the calculation. If the range is, however, too
small, it is quite possible that the correct surface is not found. To reduce this risk
you are advised to determine a value that is not too small.
Number of decimals
Here, you can define the number of decimals.
Use whole machine for collision control
Use this option to perform the collision control with the whole machine and all selected
components, e.g.: CMM, complete probe system, racks.
If this option is not selected, the collision control only checks the probe sphere for
collision. This option is in most cases much less time consuming and in many cases
sufficient.
Maximum step size for collision control
Here, you enter a value in the unit of your CAD model. Collisions with objects that are
smaller than this step size are possibly not recognised. On the other hand, a smaller
value entails a bigger calculation effort and is thus more time consuming.

Fixtures: Introduction
Situation
It is often difficult to measure certain parts of a workpiece when a workpiece fixture
obstructs the probing path. A collision of the probe with the fixture may occur.
You can, however, solve this problem, when the data for all parts of a fixture are available
in a CAD-file.
You can assign the characteristic "Fixture (only for collision control)" to the fixture.
After assigning this characteristic, the workpiece and the fixture/fixture parts can be
loaded separately.
You can define that the CAD-file with the attribute "Fixture" is not measured.
Task of the function
€
The attribute "fixture" of a CAD-model or of a part of a CAD-model is used for
the collision control.
€
The fixture shall not be used for the measurement and evaluation/calculation
in CAT1000S.
€
At your option, you can either hide or show the fixtures or parts of fixtures in
the 3D-view. This option facilitates an optimised representation of your
measurement results for the output.
Definition
In this context, "fixture" means the fixing device of the workpiece to be measured.
This holding device shall notbe used for measurement and calculation.
Prerequisites
€
If the fixture is available as a CAD-model, you can assign the attribute
"fixture".
•
The CAD-model of the fixture may be available in a separate CADfile.
•
The CAD-model of the fixture and the CAD-model of the workpiece
may be available in the same CAD-file.
€
The alignment of the CAD-model must correspond to the alignment of the
fixture.

5 = Sheet thickness
The sheet thickness in the dialogue "Measurement mode" is included in the calculation.
Therefore, the result of the calculation always refers to the side given in the CAD-model.
The sheet thickness in the dialogue "Measurement mode" does not change the probing
points.
After having confirmed the dialogue "Measurement mode", you can
€
either take on points with the joystick,
€
or define measurement points in the dialogue "Picked model points". These
are then measured in CNC-mode.
When working with models with high sheet thicknesses and small safety distances, a risk
of collisions exists.
To avoid the collision, use the option "Offset" in the dialogue "Picked model point".
In the dialogue "Picked model points" you also have the possibility to enter the offset for
the probing points, because the sheet thickness that you have entered in the dialogue
"Measurement mode" does not change the probing points.
For the offset value, the program suggests the sheet thickness you have previously
entered in the dialogue "Measurement mode".

Example:
The target / measurement point cannot be reached with the surface measurement due to
the fact that the probe touches another surface first.
In this case, the program is not using the point you have picked in the 3D-view for the
tolerance comparison.
Here, the following points are used for the tolerance comparison:
€
The nominal point is the surface point next to the measurement point not
compensated (probing point).
€
The actual point is the point that has been probed. As the material of the
workpiece prevents a direct probing path, this point is not the point that has
been clicked on in the 3D-view.

Further Differences
Calculation Effort
If you need to measure many measurement points, select the function "Tolerance of
distance", as the calculation effort for this method is considerably less than for the function
"Surface measurement".
Deviation
If you use the function "Tolerance of distance" to measure points and if a given target
point can not be reached directly, the deviation after the tolerance comparison is often a
bit bigger than after a point measurement with the function "Surface measurement".
If a direct probing is not possible for the "Surface measurement", the program
automatically looks for the next point.
Therefore, the deviation in this case is usually less.
Limitations
The function "Tolerance of distance" cannot be used
•
for Scanning and
•
for the Connection Element Surface.
The function "Tolerance of distance" can only be used for CNC-co-ordinate measurement

reference element (e.g. 'A'). In cases where GEOPAK allows the application
of the MMC, you find also the possibility to enter this reference identification.
Upon inputting the data you receive a list of the references that have already

Problem
Based on the two-dimensional information (on the screen) a three-dimensional information
shall be created.

Intermediate positions: Three methods
There are three methods to obtain the three-dimensional information required for defining
intermediate positions in CAT1000S and CAT1000P.
The methods and settings for the methods are determined in the "Settings for machine

Intersection with the model
Ö
You click directly on a surface.
€
An intersection point of the line with the model (see ill. point 1) is used to
obtain an intermediate position.
€
The point on the surface is shifted by an offset. This is a value you define in
the "Settings for machine movement" dialogue window (via menu bar,
"Settings"). The direction of the offset corresponds to the surface normal of
the surface which you have clicked on. The result is the intermediate
position.
€
This calculation is possible only when you click directly on a surface.
Current machine position
€
The second method uses the current machine position in order to calculate
the intermediate position. The "view direction line" containing the points 1, 2,
3, 7 intersects point 2 (see ill.).
€
With this method, the machine always moves only parallel to the screen view
plane.
€
The machine does not perform an uncontrolled movement along the view
direction.
€
This calculation is always possible. Consequently, there is no need for you to
click on a plane.

The third method uses an intersection of the "view direction line" containing
the points 1, 2, 3, 7 with the movement box (point 3 in the ill.) The movement
box corresponds to a clearance height for all axes.
Ö
You determine a minimum and a maximum value for each axis in the
"Settings for machine movement" dialogue window.
€
A calculation can only be performed if the "view direction line" (see ill.)
actually intersects the valid planes of the movement box, i.e. you must click a
point that is positioned within the movement box.
€
The edges of the movement box square are shown in red.
€
The calculated positions are additionally shifted away from the model by the
currently valid probe radius and the safety distance.
Refer to the topic:
Intermediate positions: One or more methods
6.11.6
Intermediate positions: One or more methods
You can use one or more methods to define an intermediate position.
You determine the method in the "Settings for machine movement" dialogue (refer to
"Dialogue: Settings for machine movement" and "Intermediate positions: Three methods").
If you select more than one method, the calculation will be performed in the following
sequence:
€
Intersection with the model
€
Move CMM parallel to view plane
€
Intersection with the movement box.
Once you have made your decision for a combination, the following applies:
€
The first successfully calculated point will be used.
€
"Successfully" means:
•
The point can be calculated.
•
With the collision check function activated, no collision of the probe tip
will occur while the CMM is moving from the current to the calculated
position.
Tip
It makes sense to combine the options "Use model points" and "Use movement
box". As a rule, the option "Move parallel to view" should not be combined with any
other option.
Error
In case that an intermediate position cannot be calculated, the following will occur,
regardless of the method used:
€
A beep will be sounding.

At the same time, an error message appears in the status line of the
CAT1000S and CAT1000P windows.

Move CMM: Confirm position
In the dialogue window "Settings to move CMM", you use the check box "Confirm

Deactivating the "Confirm position" check box causes the CMM to move
immediately to the intermediate position.
€
Activating the "Confirm position" check box causes the CMM to move to the
intermediate position only after you have confirmed the "Move machine"
dialogue.
The "Move machine" dialogue serves to check the selected co-ordinates.
If you have deactivated the check box "Confirm position" in the window "Settings
for machine movement" and if you have at the same time deactivated the
collision control, this constitutes a risk of collisions. In this case there will be no
alert before the CMM carries out any movement that may cause a collision.
€
€
In case you use the "Move machine" dialogue to check the selected coordinates, the 3D view will show a line from the current to the calculated

point table, use the menu “Window”.
This sequence of the measurement point table is used for all outputs (e.g. printout or

The input field “Position number” can only be used to sort
freeform surface points.
Example
In a series measurement (many parts of the same kind), you want to measure several
freeform surface points in a certain sequence.
This sequence is not the sequence in which CAT1000S processes the measurement task.
Reason: The measurement in CAT1000S automatically optimises the move.
By defining a position number, the desired freeform surface point is inserted at the desired
position of the measurement point table.
Please proceed as follows
Ö
Enter a "2" into the input field "Position number".
Ö
With position number 2, you measure six points.
Ö
Enter a "3" into the input field "Position number".
Ö
With position number 3, you measure four points.
The measurement point table lists your freeform surface points in the following sequence:

Please note
Measurement points without position number are assigned the number 0 by
CAT1000S. This means that the measurement point table lists these measurement

Restrict Comparison
This topic is relevant to CAT1000S only
Situation and Task
You wish to measure a surface with CAT1000S.
Click on the CAD-model in the 3D-view.
It is possible that the program does not use the picked surface of the CAD-model for the
measurement.
Possible root causes:
€
The workpiece is not correctly aligned and therefore the workpiece coordinate system is not accurate.
€
Some surfaces of the CAD-model are positioned too close to each other.
CAT1000S always calculates the distance between the measurement point on the surface
of the workpiece and the surface of the CAD-model positioned next.
Use the option "Restrict comparison" to select one or more surfaces. CAT1000S then
includes only the surfaces you have picked for the calculation (tolerance comparison).
Option "Restrict Comparison"
Use the option "Restrict comparison" to prepare a measurement.
You define the surfaces of the CAD-model that shall be used for the calculation (tolerance
comparison) later on by assigning a name to the surfaces.
After you have assigned the names, all surfaces with names can be measured.
The calculation of the measurement points (tolerance comparison) ignores all other
surfaces.
You can also use the option "Restrict comparison" to define edges. Proceed in
the same way as described for surfaces.
For using the function "Restrict comparison" during a measurement, read the help topic

Situation (see ill. 1):
There is a form deviation between the workpiece and the CAD-model.
CAT1000S always calculates the distance between the probing point on the surface of the
workpiece and the next positioned surface point of the CAD-model.
In this example: The next positioned surface point (4) is on "surface 2". However, you wish
to calculate the distance between the probing point and the surface point on "surface 1".
Solution (see ill. 2):
With the option "Restrict comparison" you determine that only the "surface 1" of the CADmodel shall be included in the calculation.
Result: CAT1000S ignores the "surface 2" and calculates the distance between the
probing point and the next position surface point of the CAD-model. This point is

Combine Several Surfaces
This topic is relevant to CAT1000S only
You can use the option "Restrict comparison" to combine several surfaces.
Application example
Due to its design, a surface is defined in several patches in the CAD-model. This is often
the case with surface feedbacks.
In this case, you can select all patches and assign only one name to all patches.
This name combines all patches of the CAD-model to a new surface.
This has the effect that the surface comparison and the subsequent tolerating only take
this one surface (consisting of all patches of the same name) into account.

Task
With the function "Create grid" you can measure many points on a freeform surface in only
one step.
This freeform surface element can include one or more CAD model planes.
Prerequisite
‰
Before you can create a grid for a freeform surface measurement, GEOPAK
must have been started.
‰
Furthermore the element “Freeform surface” must be open (also refer to
"Freeform Surface Measurement").

You should have activated the collision control before. A grid measurement
without collision control should be the exception. For information about the
topic collision control, please refer to the topic "Clearance Height".
Two options
CAT1000S offers two options to measure grid points.
‰
You can select one plane that belongs to the grid. Afterwards, the grid points
are measured on this one plane.

Plane utilisation
Under “Plane utilisation” you define the section of the grid you want to measure.
For this, you enter the values into the input fields Tmin, Smin und Tmax, Smax.
Background
Freeform surfaces can also be represented in a 2D-space. This is the S-, T-space.
In this case the S-, T-space serves to define a plane utilisation. With the min.- and
max.-values you define, how far the plane shall be utilised in the relevant axial
direction.
The standard setting for the plane utilisation is 100 percent. This means that the whole
plane is measured during a measurement.
If you want to measure only a part of the plane, you change the size of the min.- or max.values in S and T. For this, enter the desired values into the input fields.
Example:
If you want a certain distance to an edge, it does not make sense to select a plane
utilisation of 100 percent.
Input fields "Grid dimensions"
Via the input fields “Grid dimensions” you define
•
how many lines and
•
how many points per line
you want to measure.

Grid measurement and probe change
You can combine the grid measurement with the automatic probe change.
All probe changes are displayed.
Because all probe changes are performed during the measurement without
interruption, a risk of collision exists. Therefore you have to perform a visual
check of the probe changes in the 3D-view before starting the grid measurement.

Create Grid (Change Probing Direction)
This topic is relevant to CAT1000S only
Click on the "Change Probing Direction" symbol, if the surface normal in the
CAD model is wrong. CAT1000S automatically reverses the surface normal.
Reversing the surface normal
‰
The surface normal is used for calculating the probing direction. Usually the
surface normal points out of the material. This is the case particularly with
volume models (e.g. for models which have been read-in in the STEP
format.
‰
The surface normal can, of course, point into the material as well. This
happens quite often with models which are purely surface-oriented (e.g.
VDAFS, IGES). In this case CAT1000S would calculate the probing direction
not correctly. This would result in collisions.
‰
CAT1000S automatically reverses the normal in the event of recognisable
mistakes in the CAD model. CAT1000S is, however, not capable of
recognising mistakes in the CAD model in all cases.
In such a case you see right from the 3D view of the measurement point
preview whether the surface normal and the probing direction calculated
from it are correct or not. If the probing direction is wrong, you can reverse
the surface normal by a mouse click.

Clearance Height
Avoid Collisions
Usually, the co-ordinate measuring machine (CMM) takes the shortest direct way to the
target point. Through the characteristics of the part - for example an arch blocking the
direct way -, you might have collisions.
In these cases, you can define a "Clearance Height”. From the actual position, this
clearance height is driven. The CMM drives to this height up to the target, before driving to
the target point.
This way is always selected if a
€
clearance height is defined
€
€
and the collision control of CAT1000S is active. You can see that at
the icon (to the left). If you can’t see the icon, you must proceed as described
under "Program Run".
The clearance height is used in case that CAT1000S has calculated that a
clearance height is required to avoid a collision.
You always must reduce your movement speed in a way that no damages could
occur even in case of a collision.

Deactivate and hide surfaces
It can also occur, that two surfaces are overlapping, of which the one contains an internal
boundary (cut-out), the other however not. When creating an intersection, the section will
not be found.
You eliminate this failing by marking and hiding these single surfaces. In addition, you will
be active in the "Selected Surfaces" dialogue window (also see :Search Surfaces").
deactivate
If you exclude a surface from all calculations/views, but want to view it in your
drawing or documentation, use the icon.

Recover Surfaces
At any time, you can restore hidden surfaces individually or together. This is done via the
"Mark / Inactive Elements" menu and/or via "Restore Hidden Elements".
If you individually want to restore the surfaces, you can do that via a list, in which you find
the designations (names) of the surfaces.

Geometrical Elements
Along with the possibilities via the "Geometric Elements", it is no longer necessary to read
design drawings. The geometric elements such as circle, line etc. can be read in and
represented by CAT1000S.
If you have loaded a part, you recognize the elements by the coloured lines (intersection
points). If you do not want to see these lines, deactivate the function via the menu bar
"View / Vertices".
To measure e.g. a circle, proceed as follows:
Ö
Start GEOPAK and run this program in the background.

An automatic probe change is possible for the following measurement tasks:
Grid measurement
The system automatically selects the probe whose angle is the most similar to the
direction of the surface normal of the next grid point.
Circle
The system automatically selects the probe whose angle is the most similar to the
direction of the surface normal of the circle.

Cylinder
The system automatically selects the probe whose angle is the most similar to the
direction of the cylinder axes.
Cone
The system automatically selects the probe whose angle is the most similar to the
direction of the cone axes.
Please note
In any case you must have previously defined the required probes in GEOPAK.
For the elements line, plane and sphere, an automatic probe change is not
possible.
When you confirm the dialogue for grid measurement, for circle measurement, for cylinder
measurement or for cone measurement in CAT1000S / CAT1000P, the probe change is
immediately executed.
An alert message is given before the probe change is executed. An alert message of

Probe Change: Background
Definition: Swivelling range (rotating sphere)
The swivelling range of the probe (rotating sphere) is determined using the length from the
probe tip to the centre of the rotation. The swivelling range is represented in the 3D-view
as a transparent partial sphere.
Activating the options “Probe change above the clearance height” and “Set clearance
height according to direction of selected probe” has the following effects:
€
The command “Move CMM relatively” in direction of the former clearance
height is transferred to GEOPAK so that the swivelling range of the probe
touches the former clearance height.
€
Is the clearance height changed by the probe change, the command “Move
CMM relatively” in direction of the new clearance height is transferred so that
the swivelling range of the probe lies minimally above the new clearance
height.
€
Now the probe is changed.
€
The direction of the clearance height is then defined on the basis of the
direction of the changed-in probe nearest to the main axes.
On the basis of the used move box the value of the clearance height is

determined. The move box is a box that encloses the work piece. (see also
"Move Machine").
6.30.6.1
Special cases
When the tracer is positioned with an angle of 45° to the main axes,
CAT1000S / CAT1000P uses the axes in the sequence Z, Y, X.
€
Has the new probe almost the opposite direction of the old probe, the
following procedure is performed:
•
A CMM movement around the work piece is performed.
•
If one side of the move box is not permitted the opposite side of the
move box is used.
•
Are several possibilities available, the values of the move box are
used in the sequence X Min, X Max, Y Min, Y Max, Z Min, Z Max.
•
The probe is changed in the middle of the move, e.g. in the position X
Max - X Min / 2.
In case that the clearance height can not be automatically established, this has the
following effects:
€
An error message is displayed: “Clearance height can not automatically be
set”. You confirm with “OK”.
€
No probe change is executed and the CMM does not move to clearance
height.
€
If you want to continue the measurement nevertheless, confirm the
CAT1000P dialogue that you have just opened.
€
Avoid error message
You can avoid the occurrence of the error message “Clearance height can not
automatically be set” in many cases.
All “Min” and “Max” checkmark buttons of the three levels in the dialogue window “Settings
for Moving Machine” are activated in the standard setting.
However, this setting is not always useful.
In many cases you can avoid the occurrence of an error message by partially deactivating
the “Min” and “Max” checkmark buttons of the three levels in the dialogue window
“Settings for Moving Machine”.
For this, please refer to the help topic
"Dialogue: Settings for Moving Machine").
Example:
Is the work piece positioned on the table of the CMM in a way that the XY-level of the
work piece corresponds to the XY-level of the CMM, you have to deactivate the minimum
value for Z.
Is the option “Probe change above clearance height” deactivated, this has the following
effects:
The probe change is performed without prior movement of the CMM.
In this case please make sure for yourself that no collision can occur.

€
First, you only rotate and confirm.
Call the window once again, shift and confirm.
You will get other values as described above.
Shift and Rotate in CAT1000S and GEOPAK
Use this function to move and rotate the model – and not the GEOPAK co-ordinate
system. After the start of GEOPAK you will also need to align the co-ordinate system in
GEOPAK.
Hint
Pay attention to the label!
Example: If you shift the model by +5 mm in Z-direction, you have to shift the coordinate system in GEOPAK in Z-direction by –5 mm.
Don’t directly shift the co-ordinate system by the theoretic value in GEOPAK, but
re-measure the origin.
Example: You want to shift the origin of the model from one bore to an other one.
Supposed the distance between the bores is 10 mm in X-direction, then continue as
follows:
Ö
Shift the model in CAT1000S by 10 mm in X-direction.
Ö
In GEOPAK, you measure the second bore and place the origin in the
measured bore (the measured circle).
If you proceed in an other way, there will be an error, which is as big as the
distance at the part varies from the CAD model.

Best Fit
This topic is relevant to CAT1000S only
Background
The best fit calculations take a lot of time. The point cloud as a whole is shifted and / or
rotated until the optimal state will be achieved.
‰
For the criterion for the „optimal" state we take the Gauss criterion.
‰
This means that the sum of the squared distances comes to a minimum.
‰
The deviations are the distances of the actual points to the ideal surface.
Process
The process moves on step by step:
After each step, the assignment of the actual points to the individual surfaces is redefined.
The steps are executed until the achieved improvements fall below a certain limit.
Dialogue "Best Fit"
In CAT1000S
To activate the dialogue "Best fit" use the menu bar / Measure / Best fit" or click
this icon.
In GEOPAK / Learn mode
Activate the dialogue "Best fit for surface" via the menu bar / Tolerance / Best fit
for surface or click this icon.
Options in the Dialogue "Best Fit"
You can determine for the best fit
•
whether CAT1000S can shift and rotate in all directions (this will
result in the smallest deviations), or
•
whether only defined axes are allowed.

Data Evaluation
If only the rotation is allowed, you can also type in the point around which the rotation
takes place.
This point is called the reference point.
This is especially useful if the origin (this is the point of rotation) is located far from the
actual part. This is mainly true for parts, which are defined in a RPS (car co-ordinate
system).
The results of the best fit are displayed in the graphic protocol and in the standard
protocol.
Confirm best fit
If you activate the check box for "Confirm best fit calculation", the dialogue "Accept best fit
results" is shown after the best fit.
In this dialogue you can either accept or cancel the results of the best fit.
€
If you accept the best fit results, the results of the current best fit are stored.
€
If you cancel the best fit results, the current best fit is not stored and the
results of the best fit executed before the last best fit are restored.
The option "Confirm best fit" is stored in the GEOPAK CMM learn mode.
See further details under "Normal or Extended Precision".

Dialogue "Accept Best Fit Results"
This topic is relevant to CAT1000S only
In the dialogue "Accept best fit results" you can either accept or cancel the best fit results.
€
If you accept the results of the best fit, these results are stored.
€
If you cancel the results of the best fit, the current calculation is not stored
and the results of the best fit executed before the last best fit are restored.
For detailed information about the topic "Best fit in CAT1000S", read the following topics:
"Best Fit".
"Normal or Extended Precision".
7.7
Normal or Extended Precision
This topic is relevant to CAT1000S only
As each step requires some time, we distinguish between a "Normal" best fit, and a best
fit with "Extended Precision".
€
The "Normal" best fit is interrupted as soon as an improvement of 1mm of
negative deviation is reached.
€
At best fit with extended precision, the calculations are repeated as long as
no improvement can be achieved any more.
Change settings
With administrator's access rights, you can change these settings by
Ö
changing to the PartManager,
Ö
clicking on "Settings / Defaults for Programs".
Ö
Clicking in the dialogue window "Settings" on the button "CAT1000S /
CAT1000P".
€
The dialogue window "CAT1000S Settings" opens.

Data Evaluation
Ö
Activate in the section "Settings for best fit" either the function "Best fit with
higher accuracy" or "Normal best fit".
You must know:
€
The results (shift and rotation) are always given related to the origin.
€
After a best fit, the actual co-ordinate system has changed. This change is
also effective in GEOPAK.
If you only rotate, and if you have entered a point of rotation, the result may look
as if both, a shift and a rotationhad taken place. The reason for this is that: the
results are recalculated respecting the origin. This is necessary, as otherwise the
results are not comparable.

Results Window
This topic is relevant to CAT1000S only
Display Results Window
To display the results window in CAT1000S, use the menu "Window" / "Results window".
The results window contains some summarised information about …
€
Shift and turn values of the best fit, in case that a best fit has been
performed.
€
The number of measurement points in total.
€
The number of shown measurement points.
€
The maximum / minimum deviation and the mean value of the deviations.
Deviations
Deviations of surfaces, borders, positions and distances are displayed.
The box behind "Max." shows the biggest deviation. Behind it in brackets you find the
number of the point with the biggest deviation.
In the box behind "Mean" you find the mean value.
In the box behind "Min." you find the smallest deviation. Behind it in brackets you find the
number of the point with the smallest deviation.
Number of Measurement Points (only for Surfaces / Edges)
Sometimes the number of the measurement points in total and the number of the valid
measurement points differ. This is connected with the fact that measurement points are
only valid when they can be assigned to one of the surfaces.
If a measurement point cannot be assigned to a surface, it is not valid. To be assigned in
this connection means that the distance must be smaller than the tenfold tolerance. In
practice, this tenfold tolerance has proven to be sufficient. A bigger factor would
considerably increase the calculation effort.
Hint
If this is the case despite a correct probing, in most cases the error can be found in
the co-ordinate system.
Information about how to adjust your screen you find under "Graphic Output" and
"Adjust Screen".
8.2
Representation of Results
This topic is relevant to CAT1000S only
Basically, you have two ways to represent your measurement results:
‰
A numerical list,
‰
a graphics, which can also contain numerical information (see details of
"Graphical Output").
You can determine yourself whether you want to have the output vertically ("portrait") or
horizontally ("landscape") separately for both protocol types via "Settings for Graphical
Protocol", respectively "Settings / Settings for List of Results".

Results: Representation and Output
The List
You get the list via the "Output / Print List with Meas. Results" menu.
The list always contains
€
the co-ordinates of the measurement points,
€
the co-ordinates of the corresponding surface points,
€
the single deviations, and
€
the total deviation.
Furthermore, each point is marked which type of point it is: either surface point or border
point. The mark consists of one character, which we call the identifier. As the
administrator, you can define these identifiers through abbreviations such as e.g. "C"
comp. with borders. These abbreviations are pre-defined in the PartManager by Mitutoyo.
With the rights assigned through the administrator, you can change – depending on the
speech area - these identifiers.
Change Protocol Identifier
Ö
Change to the PartManager and select the "Settings" menu bar.
Ö
Call the following functions: Defaults for Programs / CMM / CAT1000S.
Ö
You come to the "Settings for CAT1000S" window. Here, you can also
determine the best fit (see details of "Best Fit").
Furthermore, see the "Specifications" subject.

Error Report
This topic is relevant to CAT1000S only
Sometimes you only need a protocol of those values, which need to be reworked or
require a setting of machine parameters, because they are out of tolerance. If you want
such a protocol (either a graphical or a numerical list), proceed as follows:
Ö
Via the "Mark" pull-down menu, you call the "Mark Points within Tolerance
Limits" function.
€
CAT1000S marks all points, which are located within their tolerance limits.
Ö
Via the "Menu Bar / Mark / Hide Marked Points", these points are invisible.
Ö
Now, you can activate the graphical or numerical protocol as required (see
topics "Graphical Output" and "Graphical Protocol ")
This setting is also stored for the repeat mode, this means via the "Output / Learn Protocol
for Repeat Mode" functions.
Hint
If there are no actual data for the protocol (e.g. if you have decided to print only the values
out of tolerance, and all values are within tolerance limits), you can select one of the two
options:
€
To print only the model or
€
no protocol.
Define this in the PartManager under "Settings / Defaults for Programs / CMM /
CAT1000S".
CAT1000S offers one more important function in the "Recover Hidden Points" window.
You get this window via the "Menu Bar / Mark / Activate Marked Points".
(< >) Using the two-way-arrow, you can exchange the status of the points: all hidden
points are visible, and all visible points are hidden. You can, e.g. delete the marked points
in one step (as a group).
Hint
In the same way, you can also use all other possibilities of the "Marked Item" menu
in order to have a clear protocol.

Graphical Protocol
This topic is relevant to CAT1000S only
The varied possibilities for graphic protocol outputs with CAT1000S are described in the
following help topics:
"Protocoldesigner in CAT1000S"
"Protocol Output"
"Layout for Protocol"
You should distinguish between the "Graphic Output" and the "Graphic Protocol", which
the user can edit. The "Graphic Output" is used to display the actual state on your screen,
respectively to print it (cf. the topic "Graphic Output". In the "Graphic Protocol", you have
further options. In the protocol, you can change the content and layout.

CAT1000S suggests five pre-defined window layouts.
Furthermore you can arrange the window layout according to your requirements. For this,
activate the radio button "User defined".
Find detailed information about this topic read the user's manual
"UM_User_Def_Info_Win_g" (German) or UM_User_Def_Info_Win_e (English). These
documents are contained in your MCOSMOS-CD.
Visibility test
After you have activated the visibility test, CAT1000S checks if measurement points in the
graphic window are hidden behind the model.
The info window relating to this measurement point is hidden when the measurement
point is not visible.
This check uses the centre of the graphic presentation of the measurement point.
Exceptions
There are only a few exceptions for which a visibility test is not possible. For these cases,
the following alternative is available:
Process
Hide the measurement points that are not shown using the function "Hide selected
measurement points". To get to this function, use the menu bar / Tools /
Measurement point.
Sort
Moreover, you determine whether the windows should be automatically sorted for the
measurement results or not.
The Flags
€
First of all, the flags are sorted (by automatic sorting) along the margins of
the graphic protocol in such a way that there are only few intersections at the
intersection lines.
€
If this is not sufficient or satisfactory, you can move each flag by the mouse.
Also see the topic "Positioning, Exchange".

Graphical Output
This topic is relevant to CAT1000S only
The "Graphical Output" option will be replaced by version 2.2 with the possibilities
described in the topics "Protocoldesigner in CAT1000S", "Protocol Output" and "Layout for
Protocol".
You should distinguish between the "Graphic Output" and the "Graphic Protocol” that can
be edited by the user (see details of "Graphic Protocol" ). The graphic output is used, to
keep hold of the actual value you see at the moment on your screen and/or to print it out.
So you can have that what you see always as a paper document or store it as a graphics
file (Bitmap).
Ö
Click via the "Menu Bar / Measurement / Store View for Repeat Mode" and
come to the window mentioned just before.

The tolerance chart window gives you an important overview regarding the measured
points and the tolerance classes.
Details
The classification for the tolerance chart depends on whether or not the same tolerance
applies for all measurement points.
If all measurement points have the same tolerance, the description shows the values in
millimetres.
In case of measurement points with different tolerances, the classes are subdivided in
"Percent of tolerance".

If you measure with CAT1000S, GEOPAK automatically creates a part
program.
‰
If you want to measure several parts with the same geometry, you only have
to repeat this part program with GEOPAK.
‰
If GEOPAK finds a measurement task of CAT1000S,
CAT1000S is automatically started.
Create Part Program
In GEOPAK learn mode, first of all, call the surface as an element. All measurement
points within this element are displayed in colours in
CAT1000S. Through the colour, you immediately get a statement if your part is well
probed, respectively not well at this position.
Furthermore
