The effect of probe misalignment and contact friction will result in
radius changes with scanning direction if a suitable calibration
procedure is not used.
Mechanical hysteresis within a probe mechanism is best
demonstrated by a bi-directional scan.
Therefore, Renishaw have decided to take the high integrity
approach of quoting ring gauge metrology using bi-directional scan
data to demonstrate the performance of the Renishaw probe and
calibration method.
