Chatter is one of the most critical errors in grinding since it can both degrade the surface quality and reduce productivity. In this paper a model for regenerative chatter during the contour grinding of optical surfaces is developed. In this model, a nonlinear formula for projected contact area is used to derive the process cutting stiffness that predicts the occurrence of chatter. Experimental results show how chatter can be minimized by properly selecting the process parameters.
