Development of CAPP based on 2.5D machining feature recognition

This paper proposes an architecture of CAPP based on machining feature recognition. The key techniques such as machining feature recognition, process planning optimization are discussed. In order to recognize the machining feature, the edges are divided into two types: convex Edge and concave Edge. The machining features are divided into four types: AOMF, HOMF, BCMF, and TCMF. The recognition process of the basic machining feature and the interactive process are given. Process planning optimization is to optimize the operation order and the machining resource. A mathematical model for process planning is given. A prototype is developed, and a example part is used for test.
