A simulation method of cylindrical plunge grinding processes is described, which has considered successive change of workpiece shape due to core elements of grinding machine. Each element is modeled and integrated in the simulation procedure. The validity of the method is shown by comparing predicted and experimental results of grinding force histories, workpiece diameter histories and final workpiece shapes. The method is also applied to reduce grinding time by controlling infeed rate. The new process with reduced time is derived and the practicality of the method is verified by conducting experiments.
