Touch Probe Cycles: Automatic Workpiece Inspection
16.7 MEASURE RECTANGLE INSIDE (Cycle 423, DIN/ISO: G423, software
option 17)

Please note while programming:

Before a cycle definition you must have programmed
a tool call to define the touch probe axis.
If the dimensions of the pocket and the safety
clearance do not permit pre-positioning in the
proximity of the touch points, the TNC always starts
probing from the center of the pocket. In this case
the touch probe does not return to the clearance
height between the four measuring points.
