Touch Probe Cycles: Special Functions
16.7 CALIBRATE TS LENGTH (Cycle 461, DIN/ISO: G461)
Please note while programming:
HEIDENHAIN only warrants the function of the touch
probe cycles if HEIDENHAIN touch probes are used.
The effective length of the touch probe is always
referenced to the tool datum. The machine tool
builder usually defines the spindle tip as the tool
datum.
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.
Datum Q434 (absolute): Datum for the length (e.g.
height of the ring gauge). Input range -99999.9999
to 99999.9999
