Spherical Shape Error Analysis and Compensation in Hard Sphere Grinding

Abstract

Abstract: In order to improve the precision of the spherical shape of hard sphere after grinding, the source of the spherical shape error in a novel hard sphere grinding machine tool was analyzed. The backup sphere grinding was proposed for the spherical shape like saddle which appears more frequently in practice. The experimental results indicate that the backup sphere grinding can decrease the spherical shape error effectively. It can benefit the hard sphere grinding greatly.

Key words: hard sphere grinding, spherical shape error, error compensation
