Abstract
A simulation method for the continuous path controlled grinding process is described in this paper. The process model allows a virtual analysis of the process parameters, different input conditions and their influence concerning workpiece geometry. The machine structure is represented by a structural dynamic system. The dynamic influence of the machine axes is considered by its control system parameters. In this machine model, the positioning error of the axes can be calculated in relation to the reference position. This is used to compute the local engagement numerically. The process force is estimated by means of an empirical grinding force model. Hence, the overall process force can be calculated and fed back into the dynamic model. Closed-loop modeling allows to rate the influence of different parameters with respect to process errors. Finally, a parameter study and the model verification under real conditions are presented on the basis of the wheel head oscillating pin grinding process of crankshafts.
