2.4 3D Touch Probe System
3D Touch probe applications
The TNC provides touch functions for application of a HEIDENHAIN 3D
touch probe. Typical applications for the touch probe system are:
• Compensating workpiece misalignment
(basic rotation)
• Datum setting
• Measuring:
- Lengths and positions on the workpiece
- Angles
- Circle radii
- Circle centers
• Measurements under program control
• Digitizing 3D surfaces (optional, only available with HEIDENHAIN plain
language dialog programming.)
The TNC must be specially prepared by the machine tool builder for the use of a 3D touch probe.
After you press the machine START button, the touch probe begins
executing the selected probe function. The machine tool builder sets the
feed rate F at which the probe approaches the workpiece. When the 3D
touch probe contacts the workpiece, it
• transmits a signal to the TNC, which stores the coordinates of the
probed position
• stops moving
• returns to its starting position in rapid traverse
