Touch Probe Cycles: Special Functions | CALIBRATE TS LENGTH (Cycle 461, DIN/ISO: G461)

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

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
