Calibration

Function
The cycle uses the calibration tool to ascertain the current distance dimensions between
machine zero (machine-related calibration) and workpiece zero (workpiece-
relatedcalibration) and the tool probe trigger points, and automatically loads them into the
appropriate data area in data block GUD6.
Values are corrected without empirical and mean values.
Prerequisite
• The approximate coordinates of the tool probe must be entered before calibration starts
• The precise length and radius of the calibration tool must be stored in a tool offset data
• Machining plane G17, G18, or G19 must be defined before the cycle is called.
• All the necessary parameters have been assigned values.

block.
This tool offset must be active when the measuring cycle is called. Tool type 120 can be
entered.
There is no special "calibration tool" type.
