Research On Process Data Application Based On 3D CAPP System

With the development and application of Computer Aided Process Planning(CAPP)technology has reduce the labor intensity of process engineers and repetitive work and improve the efficiency of process design.Along with the application of CAPP system in enterprises,the company has accumulated a large amount of process data,which contains rich process knowledge.How to reuse these process data resources efficiently is an urgent problem to be solved in the intelligentization of CAPP system.Therefore,based on the research of process data application of 3D CAPP system,the application range and efficiency of process data are improved,which is of great significance for shortening the cycle of product process design.Firstly,Overview and analysis of process data,feature definition and classification of parts in 3D CAPP system.The association model between manufacturing features and process data is established,and the correlation between process data is realized.The efficient application of process data in the CAPP system laid the foundation.Secondly,an in-depth study of the technical review of the parts was carried out.Aiming at the problem of lack of process data when using design software to assist in process review,a process review plan for parts based on process data in 3D CAPP system is proposed.In order to refine the review and improve the efficiency of review,this article from the two parts and features In this respect,the processability of the parts was reviewed,and the comprehensive performance evaluation of the parts and materials and the feature review reasoning scheme were designed.Thirdly,aiming at the problem of low data application efficiency caused by excessive accumulation of process data in the current 3D CAPP system,the intelligent push scheme of process data is designed to realize the intelligent push of relevant process data in the process of 3D CAPP system process development,and improve the process data.Application efficiency.Taking the application of process data in the process design process of a diesel engine case as an example,the effectiveness of the process data push scheme was verified.Finally,on the above research content,based on the three-dimensional machining process design system SVMAN-M of Huatian Software Co.,Ltd.,the functional modules based on the process data and the process data push function are designed and implemented.
