Phone is an integral part of our daily life communication. Our model of mobile phone design and processing electrode, for example, to explore the computer-aided mold design and processing software in the processing advantages. In this paper, CNC MasterCAM software application in the actual situation, combined with the phone model of CNC machining electrode instance, describes the environment in MasterCAM under Part Modeling, Tool Path Generation, simulation processing, post-processing program, such as CNC machining of a entire process. Electrode design of the model include mobile phone model structure size, three- dimensional modeling. CAM machining program including the type of machine selection, tool path simulation and machining parameters; digital processing technology including processing of program development, rough material selection, fixture design, tool cards, cutting the amount of calculation. In the simulation process in contrast to the rough and finish machining results, while the mobile electrode design and manufacturing model can really highlight the outstanding MasterCAM software modeling and processing functions.
