Abstract: This paper establishes an analytical solution for describing the trajectories of abrasives in polishing spherical surfaces when the motions of the tool and workpiece involve three independent angular velocities. As an example of its applications, the solution is used to show the effect of angular velocities on the trajectory coverage uniformity on a spherical surface – a key aspect for the control of a uniform material removal in a polishing operation. This solution provides a theoretical tool for the parameter selection of such machining processes.
