The Computation of Grinding Parameters for the Modified Shaper Cutter
Grinding process is regarded as the most effective way to generate the tooth profile of spur shaper cutter. However, for the purpose of generating a tip chamfer of gear, the semi-topping is always required on the tooth surface of shaper cutter, which is difficult to process by grinding wheel. This paper proposes a method to compute the profile of grinding wheel which is used to process the spur shaper cutter with a semi–topping. Firstly, translate the points on the surface of shaper cutter into auxiliary rack; Secondly, building the relationship between the coordinate system of grinding wheel and coordinate system of auxiliary rack; Lastly, the points on the surface of auxiliary rack are translated into the coordinate system of grinding wheel based on the relative motion between the grinding wheel and shaper cutter.
