Shape prediction during the cylindrical traverse grinding of a slender workpiece

In traverse grinding, the shape generation mechanism and the wheel wear process result in a complicated situation at each step on the wheel surface. The system stiffness varies with respect to the relative position of the wheel and the workpiece. Furthermore, the amount of wheel wear increases as the grinding process advances. This research analyzes the shape-generation process of a long slender shaft supported by correction steadies. The simulation model of form accuracy prediction including the grinding system stiffness with steadies is developed and the simulation analysis method of traverse grinding is proposed. Various grinding parameters essential to the form accuracy prediction model during traverse grinding (the variation of: the actual depth of cut with grinding force; the actual depth of cut with grinding amount; and the actual grinding amount with grinding stone wear rate) can be obtained from the experimental data of cylindrical plunge grinding. Finally, the results of experiment and simulation are compared to each other.
