CREATING A NEW MACHINE CONFIGURATION
The first time the function CMM Learn Mode is used it will require the relevant type of CMM to have been
configured in CMM System Manager.
Note! This will normally have been done as part of the software installation.
However if this has not been carried out upon selecting CMM Learn Mode the following error dialogue will
appear:-
Click OK and this will open CMM System Manager as shown below.
To open CMM System Manager before using CMM Learn Mode or at any time to configure a new CMM
from Part Manager select:Settings / CMM SystemManager…:-

in-front of the Tree:-
Enter the correct rotational angle of the Probe Head to
allow it to collect/return modules from/to the Tree:-.
This angle will depend on which axis the Probe Tree is
running along. Normally 0.
Important! The Docking Angle B value MUST be correctly entered or the Probe Tree
calibration program will not perform correctly and can cause errors to be
displayed.

PROBE CALIBRATION – GENERATE PART PROGRAM FOR CALIBRATION
The CMM System Manager function allows easy generation of a GEOPAK part program to calibrate the
required Probe Head Positions. This part program can then be used at any time on the CMM to reduce
calibration time and reduce / eliminate operator input.
Note! Before you Generate a GEOPAK Probe Calibration program, use the CMM System
Manager function as explained previously to build a Probe system with all the required
Probe angles (“A” and “B” angles).
Within CMM System Manager ‘right-click’ on the previously generated CMM configuration and select
Generate part program for calibration:-
The Generate part program for calibration #1 window will activate:-
The previously configured Probe System will appear in the graphical area.
The previously configured Probe Head Angles will appear as a list at the top of this window.

PROBE CALIBRATION – GENERATE PART PROGRAM FOR CALIBRATION (continued)
The fields inside the Generate part program for calibration #1 function can be completed in any order,
however it is necessary to first highlight the required Tree/s (if fitted) and Probe positions to be calibrated.
Place a cross in each Tree and Probe to be calibrated:-
Important! If you wish to Generate a part program for a Tree other than #1
(i.e. Tree #3) it is extremely important that the following is noted. Select the
required Tree as above but (as a minimum) Probe #1 of Tree #1 MUST
also be selected. Probe #1 of Tree #1 must be treated as a reference probe.
Failure to do this will cause errors in the calibration or failure of the Part
Program to repeat correctly.
Each section of this dialogue is described below along with suggested entries.
Master Ball info.
By selecting the function Manual point on top of sphere the Part Program will prompt the operator to
take a manual point on top of the Masterball
Enter the required Part Name for the
generated Part Program
(‘Trees 1,2,3’ in this example)
Total number of calibrations per Probe Head angle
Safety distance above the Masterball for each
Probe Head position change
With the fields containing the entered values as
per this example, each Probe Head position will
measure the Masterball with a circle of 4 points
around its ‘equator’, and also 1 point on top.

PROBE CALIBRATION – GENERATE PART PROGRAM FOR CALIBRATION (continued)
The Masterball can be measured as
a series of circles.
This is done by de-selecting
Point on top of sphere and then
entering the number of
circles / points per circles.
The angles represent the position of the circles to be measured from the top of the sphere in degrees.
(This will be shown on the graphic to the right of these fields).
Archive name (optional)
This field can be used to Archive the Probe data. Enter a name for the Probes as required:-
CNC parameters
These parameters set the CNC values for the generated Part Program:-
Movement speed –
Enter the speed that the CMM will move at between measurements (in
mm/s).
Measurement speed –
Enter the speed that the CMM will perform the measurements (in mm/s).
Saf. dist. for first exec. –
Enter the required ‘clearance’ value for the Stylus for the first repetition of
the Masterball measurement.
Saf. dist. for following exec. – Enter the required ‘clearance’ value for the Stylus for the following
repetitions of the Masterball measurement.
Once all the required items have been input select the OK button to generate the Part Program:The screen may ‘flicker’ briefly as the Part Program is generated. This will return the user to the CMM
System Manager. Finally select OK.
The generated Part Program will now appear in the
MCOSMOS Part Manager :-

PROBE CHANGER/RACK ALIGNMENT
Once the Probe Changer/Rack has been configured within Machine Builder it must be physically aligned
on the CMM Table to ensure it has the ability to correctly change TP20 Modules when instructed.
Important! This procedure must be carried out before initial use and also if the
Changer/Rack is removed and replaced or if it suffers a collision from the
Probe Head
Within MCOSMOS Part Manager Create a New Part and select CMM Learn Mode
Calibrate Probe Number 1 of Changer (Rack) Position 1. This can be done manually if necessary for convenience.
From the ‘drop-down’ menus select:Probe / Rack alignment...:-
This will open the Rack alignment dialogue:-
The previously configured Rack will be
available and highlighted in the list:-
Enter the Stylus length. This is the
Length of the Stylus just calibrated
(i.e. 20.000)
Select OK
This will then automatically executed the
Rack alignment program for the MCR20.
The picture dialogue shown right will appear:-
This is indicating to open the doors for
Ports 1 and 6.
Once this has been done select Continue

PROBE CHANGER (RACK) ALIGNMENT (continued)
Each picture dialogue will provide guidance as to what is required next. The next dialogue for example will
require the operator to take one Manual measurement point at the indicated location on the Rack:-
The Rack alignment program is a combination of both Manual and CNC measurement points to align the
Changer/Rack.
After each Manual point is measured the program will prompt with the next picture dialogue and/or a CNC
measurement.
Important! Ensure the area around the Changer/Rack is clear of any obstacles which
would interfere with the CNC portion of this program.
Once the Rack alignment program is complete the Changer/Rack is now aligned and ready for use.
Exit CMM Learn mode.
The previously generated Calibration Part Program can now be executed as per any other Part Program by
selecting the CMM Repeat mode icon:-
