Mold Capp Process Management And Process Data Generation Method

Based on the analysis of the character of manufacturing process of mold parts, for example, depending on handwork, many kinds of mold, small batch, fussy process design, lack of criterion, difficulty of saving mature process experience, the CAPP for mold manufacturing is being researched, which will increase the efficiency and quality of process design for mold. In this paper, the basic database for mold CAPP has been established, which is the module of process database management and module of process searches for non-molding parts and standard parts.The first work is building the general structure for mold CAPP system, Module of function and flow of system.The second work is establishing the module of process database management, according to consulting plentiful process data in process design.According to the characteristic and similarity, Mold parts classify non-molding parts, standard parts and molding parts. Because non-molding parts and standards parts have standards of industry or country, and their process are similar, so in this paper, representative process searches module is established for non-molding parts and standard parts.Finally, because of molding parts, for example, cavity/core, feed system, their shape character is related to plastic product, so they can not be standard. In this paper, according to the structure characteristic of molding parts , general framework of process design has been established, which is based on the method of Object-Oriented and process repository reasoning.
