Measure turning tool (machine-related)

Function
The cycle determines the new tool length (L1 or L2) and checks whether the difference from
the old tool length can be corrected within a defined tolerance range:
Upper limits: Safe area _TSA and
dimensional deviation check _TDIF
Lower limit: Zero offset range _TZL
If this range is not violated, the new tool
length is accepted, otherwise an alarm is
output. Violation of the lower limit is not
corrected.
Compensation strategy
The tool measuring cycle is provided for various applications:
● Initial measurement of a tool(_CHBIT[3]=0):
● Remeasurement of a tool (_CHBIT[3]=1):
Empirical values may optionally be included. The mean value is not calculated.
Prerequisite
The tool probe must be calibrated.
The approximate tool dimensions must be entered in the tool offset data:
Tool type 5xy, cutting edge position, tool nose radius,
length 1, length 2.
The tool to be measured must be active with its tool offset values when the cycle is called.
Measuring cycles
Programming Manual, 03/2009 Edition, 6FC5398-4BP10-2BA0
The tool offset values in geometry and wear are replaced.
The offset is applied in the geometry component of the length.
The wear component is deleted.
The resulting difference is calculated into the wear component (length).
