Calibrating the probe length
Calibrating a probe on a known reference surface determines the length of the probe, based on the
electronic trigger point. The stored value for length is different from the physical length of the probe
assembly. Additionally, the operation can automatically compensate for machine and xture height errors
by adjusting the probe length value that is stored.
Calibration feedrate and rotary axes
It is very important that the probe calibration is carried out at the same speed as the measurement speed,
as this automatically compensates for the xed time difference between the stylus touching the part and
the machine control reading the scale position.
If a rotary axis on the machine rotates the workpiece into the stylus then different diameter workpieces will
touch the stylus at different linear speeds. The measurement speed is therefore likely to be different from
the calibration speed and compensation will have to be carried out to account for the different speeds.
