Intelligent CAPP System For Axis Parts Of Design And Research

Process planning is a bridge link between product design and product manufacturing,the three-dimensional environment based CAPP is to achieve an important platform for process planning automation and intelligence. For improving the efficiency of product development level is important. Study abroad in CAPP system based on a careful analysis of the status qua, automatic access issues and traditional crafts phased hierarchical ordering parts manufacturing deficiency of information, based on a three-dimensional environment shaft parts in the development of two key technologies CAPP system:Extraction and integration of parts ordering information based on expert system production rules and genetic algorithms to process carried out research work.The main work is as follows:CAPP system information needed for the geometrical characteristics and process features two parts, the use of feature-based modeling approach to building parts information data structure, three-dimensional software Pro / E Dimensioning and size extract made Secondary development to achieve the CAPP system extracts the part information, part information to solve the system of identification and extraction.Inadequate analysis, expert systems reason traditional hierarchical phased CAPP system independent reasoning defects. The use of expert system production rules and genetic algorithms to solve the problem processes integrated reasoning. Avoid the shortcomings of traditional systems and expert systems independent reasoning defects.Research on the genetic algorithm in the process of ordering. Two aspects of the basic theory of genetic algorithms to do a simple exposition, and the establishment of a mathematical model based on genetic algorithms to solve the sorting process from the process of genetic algorithms and genetic algorithms running operator action. Based on such a grinder spindle parts, using genetic algorithm model to get the final results of the processing unit optimized sort grinder spindle, also verified the sort of genetic algorithm in terms of technology use is feasible. Based on such a grinder spindle parts, using genetic algorithm model to get the final results of the processing unit optimized sort grinder spindle, also verified the sort of genetic algorithm in terms of technology use is feasible.Theoretical papers in the course of practice, applied to the actual process of ordering parts to verify the practical and scientific research work in this article, have some theoretical significance and value in use.
