Paper Abstract

This paper introduces several methods to measure the dividing accuracy of a circular dividing machine. The comparative measurement method using a polygon mirror as a calibrater and a photo-electric autocollimator is studied. The characteristics of measuring with a 36-sided and a 72- sided polygon mirror are compared. The shift-position measurement is used to test the repeatability of the data measured. From the data analysis, some error factors can be found and several methods are proposed to test and reduce the dividing error.
