공작기계 슬라이더 운동오차측정시스템 개발

Measurement of straightness errors (vertical, horizontal),and angular error (roll, pitch, yaw) have been classified as difficult tasks in the machine tool metrology field. In this paper, computer aided measurement techniques are proposed using quadrant type photo pin diode. In the developed system, three photo diodes are mounted on the positioning table to detect the five degrees of movement error simultaneously. Outputs from the photo diode are analyzed in the computer and are displayed graphically.
