Research on Forming Theory of Arc Transition Edge Surface of Indexable Insert

Abstract

Generally, the indexable inserts carry out work with arc transition edges, which have a wiping effect on surface under processing and reduce the roughness of the surface. [ However, existing literatures lack research on the forming of arc transition edge surface. In this paper, the unified mathematical model and forming methods of different arc transition edge surfaces were presented, which can be used for other forming process. The mathematic models deduced would lay the most important foundation for manufacturing indexable inserts automatically. The models presented could also be extended for study on some complicated transition surfaces. Finally, the simulation was done and the result verified the theoretical derivation.
