Calibrating the effective radius and
compensating center misalignment
After the touch probe is inserted, it normally needs to be aligned
exactly with the spindle axis. The calibration function determines the
misalignment between touch probe axis and spindle axis and
computes the compensation.
The calibration routine varies depending on the entry in the TRACK
column of the touch probe table (spindle orientation active/inactive). If
the function for orienting the infrared touch probe to the programmed
probe direction is active, the calibration cycle is executed after you
have pressed NC Start once. If the function is not active, you can
decide whether you want to compensate the center misalignment by
calibrating the effective radius.
The TNC rotates the 3-D touch probe by 180° for calibrating the center
misalignment. The rotation is initiated by a miscellaneous function that
is set by the machine tool builder in Machine Parameter
mStrobeUTurn.

HEIDENHAIN only gives warranty for the function of the
probing cycles if HEIDENHAIN touch probes are used.
If you use probing functions in a tilted working plane, you
must set 3-D ROT to Active for the Manual Operation and
Automatic operating modes.
