摘要: 基于杯形砂轮回转式磨削球面原理,对各个砂轮块运动轨迹在球面分段纵切的单位圆周长度上的落点数量进行统计,发现了不同尺寸杯形砂轮磨削球面的轨迹密度及表面粗糙度的分布规律.对比2组粗糙度测试实验,验证了轨迹密度分布所推测结论.实验结果表明,杯形砂轮尺寸、球面工件尺寸是影响杯形砂轮磨削球面粗糙度分布的关键因素.

Abstract: An approach to predict distribution of spherical surface roughness was proposed based on the density of cupwheel spherical grinding trajectories. Statistics of amount of trajectories’ points in oneunit length circle were carried out aiming to segmented spherical surface. Trajectories density distribution varies with different sizes of cup wheel. Two groups of experiments were done to test the distribution of surface roughness and the conclusion above was verified by the experimental results. The final conclusion is that the sizes of cup wheel and spherical workpiece are key factors that impact the distribution of spherical surface roughness with cupwheel grinding.

Key words: spherical grinding, distribution of surface roughness, grinding trajectories, cup wheel
