Calibration of probe 1 on a surface
Workpiece probe 1 with cutting edge position SL=7 is to be calibrated on surface Z=-18 mm
in direction minus Z. The probe is inserted as tool T9, D1.
Probe lengths L1 and L2 always refer to the probe ball center and must be entered in the
tool offset memory before the measuring cycle is called, T9, D1:
Tool type (DP1):
Cutting edge position (DP2):
Length 1 - geometry (DP3):
Length 2 - geometry (DP4):
Radius - geometry (DP6):
