Datum Setting without a 3-D Touch Probe
During datum setting you set the TNC display to the coordinates of a
known position on the workpiece:
8 Insert the zero tool with known radius into the spindle.
8 Select the Manual Operation or Electronic Handwheel mode of
operation.
8 Touch the reference surface in the tool axis with the tool and enter its
length.
8 Touch the reference surface in the working plane with the tool and
enter the position of the tool center.
Setup and Measurement with 3-D Touch Probes
A HEIDENHAIN 3-D touch probe enables you to setup the machine very
quickly, simply and precisely.
Besides the probing functions for workpiece setup on the Manual and
Electronic Handwheel modes, the Program Run modes provide a series
of measuring cycles (see also the User’s Manual for Touch Probe Cycles):
„ Measuring cycles for measuring and compensating workpiece
misalignment
„
Measuring cycles for automatic datum setting
„ Measuring cycles for automatic workpiece measurement with
tolerance checking and automatic tool compensation
