ABSTRACT:
A work piece having edges comprising teeth, slots, dovetail, keyway or other irregularly shaped artifacts, can be provided with a uniform chamfer around the periphery of the work piece by bringing a grinding wheel or cutter in one single down feed at indexed intervals. The shape or profile of the grinding wheel or cutter is formed from an algorithm depending on the shape and dimensions of the work piece artifacts, such as gear teeth, etc., to provide the uniform chamfer at each slot of, for example, an internal or external gear wheel. A method of providing such a chamfer on irregularly shaped artifacts comprises forming a gear grinding wheel from the dimensions of the desired chamfer, and providing a chamfering tool or grinding wheel in accordance with an algorithm desired for the required chamfer, then bringing the gear chamfering tool in proximity to, and in contact with the edges of the work piece so as to produce a uniform chamfer on the sides and back edge. The method may include a step of moving of the cutter or grinding wheel from one side to another and tilting the cutter or grinding wheel to chamfer the back side.
