2.3 Measure workpiece (milling)
● The approximate probe length must be known in the program for collision-free positioning
● The ball radius must be known exactly and entered in the tool data. For example, this can
● The calibration surface is perpendicular to measuring axis or tool axis.
Starting position before the measurement
The probe must be positioned opposite to the calibration surface.
The distance between the probe and calibration surface should be approximately the same
as the selected measurement path (DFA).
Position after the end of the measuring cycle
According to the measuring direction (X, Y, Z), the distance between the probe and the
calibration surface is the same as the distance of the selected measurement path (DFA).
Procedure
