A three-dimensional simulation model of cylindrical plunge-cut grinding was previously devised in order to examine the wheel and workpiece wear mechanisms by means of an analysis of displacement equations in the grinding zone. In this study, the same model was applied to the grinding of sinusoidal-waved work surface. The simulation on form accuracy has been developed from some assumptions and an experimentally obtained relationship between wheel removal and workpiece removal parameters. Thus, an analogy was drawn between the experimental and simulated results. It is evident that a newly developed computer model can fairly accurately simulate the profiles of wheel surface and ground surface for an equilibrium solution. The simulation algorithm seems to give an insight into wear mechanisms and, in particular, suggests that it is important for surface profiles to control rotational speed ratio.
