A surface grinding operation is being carried out with the wheel running at a constant spindle speed. Will the wheel act soft or hard as the wheel wears down over time Assume that the depth of cut, d, remains constant and the wheel is dressed periodically. As D becomes smaller, the relative grain force increases, the wheel acts softer.
