Abstract: The key technology of manufacture for the honing wheel which is used for the honing machining of spiral gear is discussed. The calculation method for the uniformly-distributed grids of gear surface is presented. By generating these uniformly-distributed grids and computing their radius and normal vectors, the mathematical model for the limit lead of mould-drawing for each grid is built. Through computing the feasible spiral leads of each point on the gear surface, the condition for estimating interference can be achieved by judging if their intersection is empty or not. For the interference appeared, the optimized methods for the model-drawing lead and interference modification are presented. Meanwhile, the way of point-by-point and integrated shaping for the metal model and their applicability and feasibility of machining are disscussed, thus the theory is presented for the manufacture of the honing wheel for spiral gear.
