To realize the effective integration of Computer Aided Design (CAD) and Computer Aided Process Planning (CAPP) system,a new machining feature recognition method was proposed by using geometry and tolerance information simultaneously.Three kinds of information models of manufacturing resource,machined surface and machining method were constructed.Concept of cutting mode was proposed,based on which the generation principles and process for machining part surfaces were also presented.An optimization model for machining method selection was established.A fuzzy method for multi-objective optimization and ant colony algorithm were integrated to solve the model to select the best machining method for each surface.Surfaces simultaneously machined by a common type of tool and processing condition in the same setup were then recognized as a machining feature.Finally,an example was used to test the validity of the proposed method.
