CALIBRATE TS LENGTH (Cycle 461,
DIN/ISO: G461)
Cycle run
Before starting the calibration cycle, you must set the datum in
the spindle axis so that Z=0 on the machine table; you must also
preposition the touch probe over the calibration ring.
A measuring log is created automatically during calibration. The
log file is named TCHPRAUTO.html. This file is stored in the same
location as the original file. The measuring log can be displayed in
the browser on the control. If a program uses more than one cycle
to calibrate the touch probe, TCHPRAUTO.html will contain all the
measuring logs.
1 The TNC orients the touch probe to the angle CAL_ANG from
the touch probe table (only if your touch probe can be oriented).
2 The TNC probes from the current position in a negative spindle
axis direction at the probing feed rate (column F from the touch
probe table).
3 The TNC then returns the touch probe at rapid traverse (column
FMAX from the touch probe table) to the start position.
