Touch Probe Cycles: Special Functions | CALIBRATE TS LENGTH (Cycle 461, DIN/ISO: G461, software option
Please note while programming:
Danger of collision!
Cycles for coordinate transformation must not be active during
execution of the touch probe cycles.
Do not activate the following cycles before using touch probe
cycles: Cycle 7 DATUM SHIFT,Cycle 8 MIRROR IMAGE, Cycle
10 ROTATION,Cycle 11 SCALING and 26 AXIS-SPECIFIC
SCALING
Reset any coordinate transformations beforehand
HEIDENHAIN only gives warranty for the function of the
probing cycles if HEIDENHAIN touch probes are used.
The effective length of the touch probe is always
referenced to the tool reference point. The tool
reference point is often on the spindle nose (and face of
the spindle). The machine manufacturer may also place
the tool reference point at a different point.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
A measuring log is created automatically during
calibration. The log file is named TCHPRAUTO.html.
Q434 Preset for length? (absolute): Reference
for the length (e.g. height of the ring gauge). Input
range -99999.9999 to 99999.9999
