calibrating the probe. Probe types 712, 713 and 714 are not suitable for this purpose. A
positionable spindle is mandatory.
With the "Align 3D probe" measuring method, the switching direction of the probe is always
aligned to the current measuring direction. This function is recommended when high demands
are placed on the measuring accuracy. Probe types 712, 713 and 714 are not suitable for this
purpose. A positionable spindle is mandatory.
The measurement result (measurement difference) can be used as follows:
● Correction of a work offset
● Offset of a tool
● Measurement without offset
Measuring principle
The measuring cycle determines the actual value of a measuring point, taking into account the
calibration values at one edge of the workpiece referred to its zero point.
The difference between the actual value (measured value) and a specified setpoint in the
parameterized measuring axis is calculated.
