A Method of Computer-aided Design for Machine Center

Abstract

This paper studies the conceptual design of MC (machining center), and the main findings are as follows: The RW (representative workpiece) is the data source of designing an MC. The mechanical matrix of an MC can be figured out by the requirement arising from NC manufacturing of the RW, in which the layout of an MC matrix is constructed with the FPCNMT (functional parts consisting of an NC machine tool). In any CAD system, the design jobs of an MC’s layout involve three different fields. The first work deals with the preconstruction of the feature-model repository of FPCNMT, and the methods of building the repository are introduced by the author. The second design issue focuses on the construction of the mechanical matrix of an MC, in which the writer presents assembling the matrix by calling the FPCNMT based on the PP of a RW. The last job involves correctness and optimum of the layout design of the MC.
