Design And Research On UG-Based 3D-CAPP System Assembling Porcess Design Module

Computer Aided Process Planning (CAPP) takes advantage of computer to prepare the processing of parts and to turn roughcast into parts according to the requirements of drawings. By inputting the geometrical parameters (including shape, sizes and etc.) and technical parameters (including material, heat treatment, batch and etc.) of parts to be processed into computer, the computer will automatically output the processing procedure and technical methods of the parts.In the past a few years, the research on CAPP starts to focus on the basic data structure of processes and the fundamental design functions. The development interest of CAPP has changed from the automatic generating of process procedure into providing an auxiliary tool for process designers from the aspect of overall product process design and to serve the information construction of enterprise also. It directly stimulates the rapid development of CAPP applications, which generates a new generation of CAPP tool system based on human-machine interface. Certain successes have been achieved in the practical application of enterprise.As the application of 3D-CAD is getting more and more widely used in the domestic manufacturing industry, it will become one of the most popular design tools for domestic product design in the near future. As the design method keeps improving, the process design is also improving. It is urgently required by many enterprises to integrate process with 3D-CAD, to design processes and design assembling processes based on 3D-CAD and etc.Based on the project of "Design and Research on UG-based 3D-CAPP System Assembling Process Design Module" by Shanghai Guanghua Printing Machine Co., Ltd., a new CAPP assembling module is implemented through the analysis of technologies such as system structure and management function stressed by CAPP systems. The first chapter introduces the development history and current status of CAPP. The second chapter introduces UG related knowledge and the methods of secondary development using UG OPEN API. The third chapter introduces the functions and framework of 3D-CAPP system and the classification of functional modules. The fourth chapter proposes some solutions for some technical bottlenecks...
