Abstract

Surfaces of optical parts are required to be smooth. Therefore, polishing is carried out. The period of polishing process depends on the roughness of ground surface. To shorten the period of polishing process, the roughness of ground surface must be smooth. In this paper, to clarify the optimum grinding condition, maximum height roughness of traverse ground surface is analyzed theoretically utilizing the statistical grinding theory. From the view point of relationship between the grain cutting direction and workpiece feed direction, the grinding condition is classified into parallel grinding and cross grinding. And it is found that the parallel grinding has an advantage in rough grinding, and the cross grinding is suited to finish grinding.
