Design and Computation Method of Slicing Cutter with Equal Rake Angle
摘要
Abstract
In the view of the problems,the poor quality of machined surface and inconsistent machining precision of left and right tooth surfaces,the design and computation method of slicing cutter with equal rake angle is proposed.On beginning,the conjugate surface of gear surface is obtained based on the principle of conjugate surface according to the geometric feature of machining gear tooth surface and the motion relationship in slicing.Meanwhile,the sphere surface is chosen as the original rake face.To achieve the requirement of theoretical errorfree edge profile,the intersecting curve of conjugate surface and original design rake face is calculated as the cutting edge.On the basis of those works,the original rake face is redesigned by constructing a new rake face along the cutting edge complying with the principle of consistent rake angle.With this method,a series of cutting edges with theoretical error-free edge profile are obtained by means of the simulative cutter sharpening,which are used for constructing the flank face.As a result,the complete slicing cutter with equal rake angle is obtained.The calculation case is performed to verify the feasibility and effectiveness of the above developed method.At last,the conclusion and discussion are provided.关键词
