정밀 원통 부품의 4-프로브법을 이용한 온-머신 측정 기술
Abstract
In this research, an on-machine measurement system is developed, in which the multiprobe error separation (MPES) method is applied to give feedback on errors from the machining tools. To measure the roundness of the cross-sectional form-component (roundness and diameter) of the workpiece, the principle of the Fourier model-based MPES method was analyzed to solve the major problem of harmonic distortion in this technique. Using this process, the on-machine measurement system was created for machining equipment, and its performance was evaluated. The comparison between the proposed system and the general one-probe-based measuring system showed that performance of the former was 25 times better than that of the latter. This indicates the possibility of effective compensation of the motion error of rotors.
