Abstract: Plunge shaving is a high efficiency, high precision methods to finish gears. But it is difficult to profile plunge shaving cutter. A new technique, which is named for modifying and grinding the shaving cutter on the shaving machine, is put forward. Its principle is that a diamond dressed gear is clamped in place of the workpiece in the machine, and profiles the cutter as shaving. The mesh theory of the technique has been analyzed. The equation of mesh, equation of gear flank of shaving and profiling are obtained and the analysis of example is presented. It is proved that the new technique is an applied method with many advantages by experiments.

Key words: Axianl gear shaving, Cutter profiling, Diamond dressing gear, Mesh analysis
