Abstract

The concept of rotation accuracy of serrated- tooth indexing table (STIT) is different from that of conventional rotating table because STIT is an intermittent rotating table. The rotation accuracy of STIT is mainly measured by the centring error. Based on the fundamentals of interferometry a new setup to measure the centring error of SPIT was developed. It is a non-contact precision measuring setup with which the measurement is not affected by axial rise and fall of working table of STIT therefore many difficulties due to contact-type measuring methods were overcome. The experimental results are given in the paper.
