Touch Probe Cycles: Automatic Kinematics Measurement | KINEMATICS GRID (Cycle 453, DIN/ISO: G453,
option)

Please note while programming:

For Cycle 453 KINEMATICS GRID the software
option 48 KinematicsOpt and software option 52
KinematicsComp are required.
This feature must be enabled and adapted by the
machine tool builder.
The machine tool builder defines the storage location of
the compensation table (*kco).
Before starting the cycle make sure that M128 or
FUNCTION TCPM is deactivated.
Cycle 453, as with 451 and 452, is exited with an active
3-D ROT in automatic mode that matches the position of
the rotary axes.
Position the calibration sphere on the machine table so
that there can be no collisions during the measuring
process.
Before defining the cycle you must set the preset in the
center of the calibration sphere and activate it, or you
define the input parameter Q431 correspondingly to 1 or
3.
If machine parameter mStrobeRotAxPos (No. 204803)
is not equal to –1 (M function positions the rotary axis),
only start a measurement if all rotary axes are at 0°.
For the positioning feed rate when moving to the
probing height in the touch probe axis, the TNC uses the
value from cycle parameter Q253 or the
whichever is smaller. The TNC always moves the rotary
axes at positioning feed rate Q253, while the probe
monitoring is inactive.
In every probing process the TNC first measures
the radius of the calibration sphere. If the measured
sphere radius differs from the entered sphere radius
by more than you have defined in machine parameter
maxDevCalBall (No. 204802) the TNC shows an error
message and ends the measurement.
Programming in inches: The TNC always records the log
data and results of measurement in millimeters.
If your machine is equipped with a controlled spindle,
you should activate the angle tracking in the touch probe
table (TRACK column). This generally increases the
accuracy of measurements with a 3-D touch probe.
