Tilt - Fixed Sensitive Radial
Tilt-Fixed Sensitive Radial measures variations in the tilt of the spindle during rotation. Data is collected from either the X, X2 or Y, Y2 probe pair. Using the readings from each probe and the distance between the probes, the tilt of the spindle is calculated at each angular location measured. The results are reported in µradians.
It evaluates the following aspects of machine tool performance and their degradation as distance from the spindle is increased:
