About the EasyProbe cycles

About the EasyProbe cycles
This guide describes how to use the Renishaw EasyProbe cycles. They are intended for
setting up simple jobs and measuring tasks.
By using these cycles, you will not have to create a program to position the probe prior to
the setting cycle call. The software allows you to position the stylus at a suitable start
position, in either the jog or handwheel mode, before running the cycle. Alternatively, the
EasyProbe custom cycles can be written into a part program for automatic programming
applications.
The main cycle is:
O9023 (REN START/SETUP)
This cycle is supported by the service macros listed below. Together, they form a
complete standalone software package that can be loaded into the control part-program
memory area.
O9770 (REN PROTECTED MOVE)
O9771 (REN BASIC MEASURE)
O9772 (REN OFFSET TYPE)
O9773 (REN SURFACE)
O9774 (REN FEATURE)
O9775 (REN ANGLE/4TH AXIS)
CAUTION: The EasyProbe cycles should be carefully tested for safe operation in
both MDI’ and ‘program’ mode during the commissioning. This will ensure they
are compatible with your machine configuration. If you use the cycles without first testing
them thoroughly for compatibility, serious mispositioning and damage may be caused (see
the section “Testing the software” later in this guide).
!
How much memory is required?
Loading all the cycles requires approximately 6.0 KB (15.0 metres) of part program
memory.
If you do not expect to use any of the macros listed below, do not load them.
O9773 (REN SURFACE)
0.6 KB (1.5 metres) of memory
O9774 (REN FEATURE)
1.2 KB (3.0 metres) of memory
O9775 (REN ANGLE/4TH AXIS)
0.9 KB (2.3 metres) of memory

Calibrating a spindle probe
Control parameter setting – retaining the common variables
on reset
Your machine controller must be set to retain common variables on reset. This is a
parameter setting that allows the angle measure cycle to work, and lets you see the
results written to these variables after the cycle has finished. For detailed information, see
the Readme file that is supplied with the EasyProbe software.
Calibrating a spindle probe
Before a spindle probe is used on a machine tool, it must be calibrated. Calibration
ensures that the length of the probe and the size and centre position of the stylus ball are
known. With this knowledge you can be sure that measurements taken with the probe will
be accurate.
The EasyProbe cycles have built-in calibration routines. Use these whenever a probe
needs to be calibrated.
When should a spindle probe be calibrated?
A probe should be calibrated in the following circumstances:
●
Whenever a new stylus is fitted.
●
Whenever the probe is exchanged with one from a different machine.
●
Whenever a new shank is fitted to the probe.
●
If it is suspected that the stylus has become distorted. For example, due to a collision
with part of a feature.
●
If any on-centre adjustment has been performed.
●
If very tight tolerances are to be achieved during workpiece set-up.
Publication No. H-2000-6181
Calibrating a spindle probe
How do I calibrate a probe?
Three steps are involved in calibrating a spindle probe.
Step 1
Determine the length of the probe stylus assembly. See “Example 1 –
Calibrating the probe length”.
Step 2
Determine the relationship between the {x,y} centre of the stylus ball and the
machine spindle (the X and Y stylus offsets). See “Example 7 – Calibrating the
probe XY offsets”.
Step 3
Determine the effective size of the stylus ball (the ball radii). See “Example 8 –
Calibrating the probe stylus ball radii”.
Steps 2 and 3 can be carried out either as individual operations, as described above, or
combined into one operation (this is the recommended method). See “Example 6 –
Calibrating the probe XY offsets and stylus ball radii (combined operation)”.
Using the ‘C’ input
Instead of having separate calibration routines, the standard measuring cycles are used
with the ‘C’ input to calibrate the probe.
●
C1. – use this input to calibrate the probe for either length or stylus offsets/radii.
●
C2. – use this input to calibrate the probe stylus offsets.
●
C3. – use this to calibrate the probe stylus radii.
Publication No. H-2000-6181

Calibrating a spindle probe
Calibrating using experience values
Depending on circumstances, a probe might not always need to be calibrated precisely.
Instead, experience values can be used. To calibrate using experience values, first
mechanically centre the probe stylus so that it runs true. Next, enter the values directly via
the keyboard.
Do this as follows:
1.
2.
Enter experience values for the stylus ball radii.
●
Actual (experience) stylus radii values are typically 0.030 mm (0.0011 in) less
than the physical radii values.
●
For details of where these values are stored, see the section “Common
retained variables”.
Set the XY offsets to zero (0).
●
3.
For details of where these values are stored, see the section “Common
retained variables”.
Set the probe tool offset register to the length of the probe/stylus assembly.
●
Enter the length into the tool offset register that you have allocated to the
probe tool holder.
If you use this method, ignore the calibration procedures described previously and all
further examples of probe calibration.

Common retained variables
The common retained variables used depend upon the inspection software option that is
selected during the initial generation of the EasyProbe software.
●
●
Variables for Inspection Plus software are used when either:
●
No Renishaw inspection software is currently installed, or
●
Renishaw Inspection Plus software is currently installed.
Variables for the standard Renishaw inspection software are used when the
standard inspection software is currently installed.
Inspection Plus calibration data variables
Each of the following values is found during the calibration process.
#500 = X axis stylus ball radius.
#501 = Y axis stylus ball radius.
#502 = X axis stylus ball centre offset.
#503 = Y axis stylus ball centre offset.
Publication No. H-2000-6181
Common retained variables
17
#506 = Stylus backoff factor adjustment.
This should be optimised during installation. Reducing the value
decreases the distance the stylus will back off from the surface before
making a final measuring move. When the software is set for a one-touch
measuring move, #506 is not used. (See the section “Customising the
software”, variable #118.)
Standard inspection calibration data variables
Each of the following values, with the exception of #506, is found during the calibration
process.
#500 = X+ axis stylus ball radius.
#501 = X– axis stylus ball radius.
#502 = Y+ axis stylus ball radius.
#503 = Y– axis stylus ball radius.
#504 = X axis stylus ball centre offset.
#505 = Y axis stylus ball centre offset.
#506 = Stylus backoff factor adjustment.
This should be optimised during installation. Reducing the value
decreases the distance the stylus will back off from the surface before
making a final measuring move. When the software is set for a one-touch
measuring move, #506 is not used. (See the section “Customising the
software”, variable #118.)
NOTE: When EasyProbe files are generated using the Haas USA option, the range
of common variables (#100) and common retained variables (#500) are different
from those shown above.
When using this option, all #100 variables are incremented by 50 and the #500
variables by 56. For example, the 4th axis system number setting variable #115
becomes #165 and the probe tool offset number variable #120 becomes #170.
Similarly, the X+ axis stylus ball radius #500 becomes #556 and the backoff factor
#506 becomes #562.
This is to comply with current Haas USA recommendations for probe variable use
and should avoid conflicts with other systems on the machine.

Customising the software
Customising the software
Customising features are provided in the macro O9023 (REN START/SETUP). This
involves adding suitable probe start and stop codes, and editing the default values of
some of the common variables used in the software.
(START CODES)
Enter suitable start-up codes at the top of the macro, when
applicable, to switch on the probe. A spindle orientation code, M19,
is already included to consistently position the spindle correctly each
time the cycles are used.
Start codes will usually be M-codes.
(STOP CODES)
Enter suitable stop codes at the end of the macro, when applicable,
to switch off the probe.
Stop codes will usually be M-codes.
#115

4th axis system number setting and direction (i.e. clockwise or
counter-clockwise). This must be set during the installation if using a
4th axis option (see the section “Testing the software”). The setting is

This is used to read and apply the active tool offset values.
#118
=
Measuring feedrate. The default value of 30 mm/min (1.181 in/min) is
suitable for general applications on most machines using a two-touch
measuring move.
NOTES: Feedrate values must always be entered in mm/min, even
if the Imperial (inches) mode is being used on the machine.
Be aware that measurement accuracy can be compromised by
increasing the measuring feedrate (see the section “Testing the
software”).
Machines with an ‘High Speed Skip’ (fast) measuring input can be
run at faster feedrates – typically 500 mm/min to 1000 mm/min
(20 in/min to 40 in/min).

Once the feedrate is increased above 100 mm/min (3.94 in/min), the
cycles change to one-touch measuring. Tests may be required to find
the optimum feedrate for your application.
#119

Fast feedrate used for protected positioning in XY axis (default
5000 mm/min).
Calculated: Z axis is (#119*.6=) 3000 mm/min.
First-touch measure is (#119*.3=) 1500 mm/min.

Testing the software
After you have finished customising the software, or even if no changes have been made,
you should carefully run the cycles to make sure they are compatible with the machine.
You are recommended to carry out each of the tests described below as appropriate.
Test 1:
Z axis moves
Run a Z measure cycle clear of any obstruction (ideally at the Z home position). Check
that the axis only moves the incremental programmed distance, and not a large value that
includes the probe length.
If the probe is not triggered, a ‘Probe Fail’ alarm should occur at the end of the move.
Run this test in MDI mode and under program operation. Also run this test immediately
after switching on the machine but before you have selected a tool offset.

Testing the software
Test 2:
Measuring accuracy
Test that the measuring accuracy is suitable for your application. You must do this if you
have changed the default measuring feedrate.
This test is usually achieved by making repeated measurements on a surface, while
starting the moves from different standoff positions.
Test 3:
Fast feedrate optimisation
Test that the fast feedrates are optimised for your machine. For safe operation the
machine must be able to stop during a measuring move within the overtravel of the probe.
The default feedrate values used are usually suitable for small to medium size machines.
TIP: Test the feedrate by positioning the probe stylus to trigger during a skip move on the
edge of a surface, so that the stylus will skid off the surface and prevent excessive
overtravel.
Test 4:
Updating the work offset
If the 4th axis measuring feature is to be used, check that the correct work offset is
updated and that it is applied in the correct direction, i.e. clockwise or counter-clockwise.
The axis direction and axis number are set inside macro O9023 using #115 = 4, 5 etc. or
#115 = -4, -5 etc.

Angle data
Angle data
The normal mathematical convention for angles is used. This means the specified angle
or resultant angle is a positive (counter-clockwise) angle (see the following figures).
This may cause confusion on a machining centre where the normal operator viewpoint is
from the Y– direction (typical) for rotations around the Y axis.
Output – angle (#139)
The cycle calculates the angle using the controller ATAN function, without any
manipulation of the result.
This is an absolute value that is measured as follows:
●
‘A axis’ rotation (around the X axis) is measured from the Y+ axis.
●
‘B axis’ rotation (around the Y axis) is measured from the X+ axis.
●
‘C axis’ rotation (around the Z axis) is measured from the X+ axis.
Output – angle error (#144)
The cycle calculates the angle error from the ‘Aa input’ angle. The result is always given in
the range ±90 degrees.
4th axis work offset adjustment
This is always adjusted by the #144 value, which means the shortest distance (angle
error) used for the update.
To change the update direction to the 4th axis, see the section “Customising the
software”, variable #115.

(This is a reset condition.)
Message
93 PROBE FAIL
593 PROBE FAIL
Action
The probe did not hit the surface during the measure move, or the signal
is not received or actioned by the control.
This alarm is sometimes given if the surface is hit close to the target
overtravel limit. The condition gets worse with higher measuring
feedrates.
Correct the error and try again.
(This is a reset condition.)
Message
95 ANGLE DATA ERROR
595 ANGLE DATA ERROR
Action
The macro could not process the angle data provided.
Reasons:
●
Two surface measurements are taken at the same position.
●
Only one axis positioning move is allowed (not counting the
measuring axis) between the two surface measuring points.
●
Using the Aa input when not trying to measure an angle.
Position correctly from the current position, and try again. (This is a reset
condition.)
