<p>A method and apparatus for grinding a cam (12) with a cam lobe is provided. Rotation of the cam (12) is synchronised with the infeed/outfeed movement of a grinding wheel (10). Control means measures the relative rotational and lateral positions of the cam (12) and grinding wheel (10). The movement of the grinding wheel (10) relative to the cam (12) is controlled to roughly grind a desired cam profile. Finish grinding may be by way of grinding wheels or abrasive belt. Surface hardening may be applied to the ground cam before the finish grinding step.</p> |
