Touch probe cycles for automatic operation
Besides the touch probe cycles, which you can use in the Manual and
Electronic Handwheel modes, the TNC provides numerous cycles for
a wide variety of applications in automatic mode:
„ Calibrating the touch probe (Chapter 3)
„ Compensating workpiece misalignment (Chapter 3)
„ Setting reference points (Chapter 3)
„ Automatic workpiece inspection (Chapter 3)
„ Automatic workpiece measurement (Chapter 4)
You can program the touch probe cycles in the Programming
operating mode via the TOUCH PROBE KEY. Like the most recent
fixed cycles, touch probe cycles use Q parameters with numbers of
400 and above as transfer parameters. Parameters with specific
functions that are required in several cycles always have the same
number: For example, Q260 is always assigned the clearance height,
Q261 the measuring height, etc.
To simplify programming, the TNC shows a graphic during cycle
definition. In the graphic, the parameter that needs to be entered is
highlighted.
