Overview

 
Machine

The control must be specifically prepared by the machine manufacturer for the use of a 3D touch probe.

HEIDENHAIN guarantees the proper operation of the touch probe cycles only in conjunction with HEIDENHAIN touch probes.

In order to precisely specify the actual trigger point of a 3D touch probe, you must calibrate the touch probe; otherwise the control cannot provide precise measuring results.

 
Tip

Always calibrate a touch probe in the following cases:

  • Initial configuration
  • Broken stylus
  • Stylus replacement
  • Change in the probe feed rate
  • Irregularities caused, for example, when the machine heats up
  • Change of active tool axis

The control assumes the calibration values for the active touch probe directly after the calibration process. The updated tool data are immediately effective. It is not necessary to repeat the tool call.

During calibration, the control determines the effective length of the stylus and the effective radius of the stylus tip. To calibrate the 3D touch probe, clamp a ring gauge or a stud of known height and known radius to the machine table.

The control provides calibration cycles for calibrating the length and the radius:
