How to further improve (or an organic integration) used by the applications, and how to solve using a single application of the system functions when inpatibility issues, these will bee the focus of attention of many to use side. In this paper, take the preparation of mechanisms for process planning for example, briefly describing and analyzing the current application of several advanced technologies’ basic method and its integrated applications, and discussing how to achieve puteraided process design and software development platform for CAPP to a unified development. 1. Group Technology(GT) Group technology (GT) is to wide a variety of various singlepiece and small batch production of spare parts, and according to its shape structure, technical requirements, processing methods of the similarity of the parts is divided into several groups. Then choose a representative part (which can actually exist, and also some of the hypothetical, but must include all parts of the processing group elements)in the selected parts of each group. According to the representative part of this process to develop a typical order and we select and design a set of machine tools and process equipment. And we unite them with a special construction section or workshop. When the processing of an object bee from one part into another part within the same group, due to the similar of technical requirements, structure, process, you do not change the processing method and processing equipment, and even controlling the cam, block railways and industrial fixtures are do not change. It is simply to make adjustments, will be processing [1,2]. According to production organize ponents into groups, we accord the parts of the structural characteristics, process characteristics and processing equipment characteristics to group, classification and code for each of the ponents, and then establish the typical ponents of each type of library and the processing technology of group library. Processing technology to develop parts in groups of two ways: 1) The virtual part method. In a parts group, the first we design a part of this group which can contain all the geometrical features of the virtual part, and require the tribe owns the processing of all the parts needed for processing the surface. Then we press the virtual part to technological design. That is the group technology of group parts. 2) The posite process route method. Firstly , we find a the most plicated structure, the longest part of process lines represented in the part family, and then join in the other parts which is representative and not processes in the family. Obtain a whole family to meet the processing requirements of plex parts process route.
