Abstract
A method for modifying plunge shaving cutters aims to modify a plunge shaving cutter through a grinding tool. The plunge shaving cutter has a plurality of helical teeth spaced from each other. The helical teeth have a machining-intended side. The method of modification includes the steps of: positioning the plunge shaving cutter on a gear forming grinder with the machining-intended side in contact with the grinding tool; moving the plunge shaving cutter according to a variable rotation amount and a first variable movement amount; moving the grinding tool according to a second variable movement amount to perform a helical movement against the plunge shaving cutter and a modification process on the machining-intended side. Thus the existing gear forming grinder can be applied to the plunge shaving cutter for machining to improve machining speed.
