Abstract

Abstract:

In order to improve the grinding accuracy and efficiency of large diameter aspheric surface, a generated grinding method for aspheric surface based on the normal track is proposed, and a motion control model is designed. In grinding process, the rotation centerline of grinding wheel spindle always coincides with normal line of grinding point on aspheric surface. A detecting device is designed for tracking shaping precision in real-time, and a mathematical model and a related grinding process for automatic compensation of grinding wheel wear are established. Results show that the proposed method can be used to avoid the principle error of grinding motion trajectory, make the motion mechanism simple, and ensure the motion accuracy; grinding ratio and grinding efficiency are increased by using the end face of the grinding wheel for aspheric surface grinding.

Key words: manufacturing technology and equipment, large diameter SiC aspheric surface, generated grinding, normal tracking, real-time detection
