Measuring Cycles for Turning Machines
6.6 CYCLE994 workpiece: 2-point measurement
The offset must take the empirical value in memory _EV[2] into consideration for T 8, or
_EV[3] for T 9. Mean value calculation _MV[2] or _MV[3] and inclusion in calculation are also
to be used. This tool offsets will therefore affect the production of the next workpieces or
possible remachining.
Clamping for workpiece:
Zero offset, with settable ZO G54: NVz
Workpiece probe 1, used as tool T1, D1, is to be used.
The probe is already calibrated. Arrays for workpiece probe 1: _WP[0, ...]
The following is entered under T1, D1 in the tool offset memory:
Tool type (DP1):
Cutting edge position (DP2):
Length 1 - geometry (DP3):
Length 2 - geometry (DP4):
Radius - geometry (DP6):
