Gear shaving, which is widely used in mass production gears, is a free-cutting process that removes small amounts of metal from the gear tooth working surface. Plunge shaving is an advanced gear finishing technique first developed in the late 1960s, whose advantages over the conventional gear shaving processes include increased productivity, good accuracy, long tool life, and a simple machine structure.This book proposes an approximate guidance for choosing the proper operation cylinder, helix angle, and geometric data for the cone grinding wheel for finishing or resharpening the plunge shaving cutter.The surface roughness of the work gear after plunge shaving, which is primarily affected by the arrangement of the serrations, can be improved if the cutting edge of the serrations is arranged as much as possible to perform upcutting.
