Function overview

Function
With milling machines and machining centers, the probe is usually loaded into the spindle
from a tool magazine.
This may result in errors when further measurements are taken on account of probe
clamping tolerances in the spindle.
The probe trigger points must be determined in the axis directions that are dependent on:
● the probe ball diameter:
● the mechanical design of the probe.
● speed at which the probe hits an obstacle.
With this calibration cycle it is possible to calibrate a workpiece probe in a hole (axes in the
plane) or on suitable surfaces for a particular axis and direction.
