In a method of grinding a component such as a cam, a reduction in the finish grinding time is achieved by rotating the component through only a single revolution during a final grinding step and controlling the depth of cut and the component speed of rotation during that single revolution, so as to maintain a substantially constant specific metal removal rate during the fin al grinding step. The headstock (12) velocity can vary between 2 and 20 rpm during a single revolution of the cam during the final grinding step, with t he lower speed used for grinding the flanks and the higher speed used during th e grinding of the nose and base of the cam. Using a grinding machine (10) havi ng 17.5 kw of available power for rotating the wheel, and cutting a grinding wheel in the range 80-120 mmdiameter, typically the depth of cut lies in the range of 0.25 to 0.5 mm.
