Abstract

A multi-point method for spindle error motion measurement is proposed in the paper. The radial error motion of the spindle is measured by 4 probes, where as the axial and tilt ones by 5 probes. Roundness error and flatness error of the specimens used for measuring the spindle error motions are separated and have little effect on the accuracy of spindle error motion measurement. For assuring high accuracy of measurements techniques for determining the actual angular positions of the probes and hardware of measuring system have been also developed. The proposed method can be used for real-time spindle error motion measurement with sub-micron accuracy.
