Study of Cutting Tool Path of Manufacturing Equal Base Circle Bevel Gear

Equal base circle bevel gear is a new kind of curve gear based on numerical control technology. Now its manufacturing method has no experienced dada that can be referenced. The traditional manufacturing method is of high cost and low efficiency. Cutting tool path of manufacturing above mentioned gear was analyzed through simulating NC machining in PC, and it presents relative motion of cutting tool path. According to relative motion of cutting tool path, practical machining has been accomplished in the laboratory, and the result is in accordance with the result of computer simulation. It has been proved that this theory model is correct, and can be used to practical NC machining, which is important to complete this new gear manufacturing technology.
