Calibrate tool probe (machine-related)

Function
The cycle uses the calibration tool to ascertain the current distance dimensions between the
machine zero and the probe trigger point and automatically loads them into the appropriate
data area in data block GUD6 (_TP [ ]fields).
Values are corrected without empirical and mean values.
Note
If no special calibration tool is available, a turning tool can be used instead for calibration of 2
sides of the probe (see Chapter "Determining dimensions of calibration").
Requirement
Since no specific tool type is available for the calibration tool, the 8th digit of _MVAR
indicates whether a calibration or turning tool is to be used for calibration (see CYCLE982,
measuring variants).
Lengths 1 and 2 and the radius of the calibration/turning tool must be known exactly and
stored in a tool offset data block.
This tool offset must be active when the measuring cycle is called. A turning tool must be
specified as the tool type (type 5xy). Calibration is possible with cutting edge positions SL1,
SL2, SL3 or SL4.
