Abstract An approach to predict distribution of spherical surface roughness was proposed based on the density of cupwheel spherical grinding trajectories. Statistics of amount of trajectories’ points in oneunit 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 cupwheel grinding.
