Overview

Task

This instruction describes:

• the automatic calibration of the touch probe.

Possible applications

The characteristic touch probe parameters are determined by measuring geometric objects with known properties.

The determining parameters include:

• the length of the touch probe,
• the radius of the touch probe sphere
• and the shift of the touch probe along the X and Y axes.
  

These are electronic variables that integrate the speed-dependent trigger offsets during measurement and may therefore deviate from the geometric values.

These parameters are used by the measurement cycles to automatically correct the measurement result. Correct calibration is therefore essential for accurate measurement results. Further details on the correction and the resulting requirements for the measurement motion are contained in the section Requirements for measuring.

The various output variables are defined in greater detail in the subsections for each of the cycles.

Programming

The cycles are called with the L CYCLE[..] function and the required parameters are taken directly from the NC program.
A more detailed description of the call is provided in the subsections for each of the cycles.
