[Abstract]:Based on the key industry project of Zhejiang Province, "Digital Design Technology and Application of injection Molding Machine based on Product platform", the modeling and variant design technology of part family based on tabular feature table is introduced in this paper. The technology of part family master document and variant design and part family NC master document establishment and variant design are studied. The overall frame of part family modeling and variant design system is constructed according to the present situation of enterprise design and production. And develop a prototype system to effectively help enterprises implement parts standardization work. The first chapter analyzes the research background, scope, goal and significance, and summarizes the research progress in parts family modeling, part family variant design, process variant design, numerical control variant design, at home and abroad. Furthermore, the main research contents and organization structure of this thesis are given. In the second chapter, the basic principle of part family variant design based on SML is introduced, and the requirement of part family modeling and variant design system is analyzed according to the existing design and production process of enterprise. On this basis, the overall design of the system is carried out, and the overall structure, function model, information model, interface design and application flow of the system are introduced. In the third chapter, the geometric modeling and variant design of part family are studied. In this paper, the idea of encapsulation is adopted to encapsulate the object characteristic table of part family and 3D CAD model. Through parameter extraction, parameter association, existing configuration adding, the rapid variant design of part family is realized, and the blank model is generated at the same time. The process of geometric modeling and variant design of part family is established in detail. In the fourth chapter, the part family process modeling and variant design are studied, the concept of geometric feature process is put forward, the part family information model supporting process modification is given, and the process of process modification and key technology are studied. The process master document establishment and variant design flow are designed, and the application technology of process modification is introduced in combination with the examples of the two plate families. In the fifth chapter, the numerical control modeling and variant design of part family are studied. The idea of the fourth chapter is followed, the information model of part family is given, and the technical method of numerical control modeling and variant design is studied. Finally, the research results of this paper are given, and the direction of further research is prospected.
