Axial Error Motion
Axial Error Motion acquires distance data from one probe in the Z axis (typically channel 3). The probe measures the axial motion of the spindle. Angular position data is also required and is obtained from the eccentricity motion measured by another probe in the X or Y axes or an index or encoder signal. It measures changes along the axis line and evaluates the following aspects of machine tool performance:
