Abstract:

In order to improve the uneven surface roughness due to the different curvatures, the relationship among envelope height, feed rate, rotational speed and curvature of workpiece was analyzed based on equal-envelope-height grinding method. The results show that, low feed rate of grinding wheel and high rotational speed of workpiece are helpful to obtain smaller envelope height. And the smaller the radius of workpiece curvature, the more different the surface roughness. Besides, it is an effective method to solve this problem by changing the feed rate. The feed rate should be changed directly proportionally to radius of workpiece curvature. So, when grinding the revolving curved surface, diamond roller and various speeds at different radius of curvature are greatly helpful to the uniform surface roughness and surface quality.
