Touch probe cycles in the Manual and Electronic
Handwheel modes
In the Manual Operation and El. Handwheel modes, the TNC provides
touch probe cycles that allow you to:
„ Calibrate the touch probe
„ Compensate workpiece misalignment
„ Set reference points
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 and
Editing 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 (see figure at right).
