Trajectory Simulation and Material Removal Rate for Double Side...

A computerized kinematical model for double-sided fine grinding accounting for piece rotation inside the workpiece carrier was developed. Simulated trajectories for random points located on the end faces of the workpiece, both in a fixed global coordinate system and in each wheel's rotating coordinate system, were predicted. Experiments using different grinding kinematics and coolant conditions were carried out. A strong correlation was found between the predicted length of trajectory and the experimental material removal rate. Conclusions on the optimization of the double-sided fine grinding process were deduced. Authors: I. D. Marinescu (University of Toledo), C. Spanu (Gaiser Tool Co.), M.
