Touch Probe Cycles: Automatic Kinematics Measurement | Prerequisites

19.2 Prerequisites

The following are prerequisites for using the KinematicsOpt option:
The software options 48 (KinematicsOpt), 8 (Software option 1)
and 17 (Touch Probe function) must be enabled.
The 3-D touch probe used for the measurement must be
calibrated.
The cycles can only be carried out with the tool axis Z.
A calibration sphere with an exactly known radius and sufficient
rigidity must be attached to any position on the machine table.
HEIDENHAIN recommends using the calibration spheres
KKH 250 (ID number 655475-01)
655475-02), which have particularly high rigidity and are
designed especially for machine calibration. Please contact
HEIDENHAIN if you have any questions in this regard.
The kinematics description of the machine must be complete
and correct. The transformation values must be entered with an
accuracy of approx. 1 mm.
The complete machine geometry must have been measured (by
the machine tool builder during commissioning).
The machine tool builder must have defined the machine
parameters for CfgKinematicsOpt (No. 204800) in the
configuration data. maxModification (No. 204801) specifies
the tolerance limit starting from which the TNC is to display
a message if the changes to the kinematic data exceed this
limit value. maxDevCalBall (No. 204802) defines how much the
measured radius of the calibration sphere may deviate from
the entered cycle parameter. mStrobeRotAxPos (No. 204803)
defines an M function that is specifically configured by the
machine manufacturer and is used to position the rotary axes.
