薄板叠层粘接模具制造技术中的CAD研究

Study on CAD Approach in Die's Manufacturing by Sheet Metal Layer for Layer through Gluing

基于材料生长制造的原理提出了薄板叠层粘接模具结构的新构思，着重讨论了模具型面创成与离散化处理的ＣＡＤ方法，分析了ＣＡＤ模型分层、层面信息转换与传递以及薄板叠层粘接结构的力学特性。

Based on the principle of material incress manufacturing, a new idea of the die's construction manufactured by sheet metal layer for layer through gluing is presented, and a CAD approach of the die's three-dimensional surface creating and the scattering handling is discussed in this paper. It is also analysised that layer's separation of the three-dimensional CAD model, change and transmission of separating layer's data, and mechanical properties of die's construction manufactured by sheet metal layer for layer through gluing. The results of the research indicate that die's manufacturing by sheet metal layer for layer through gluing is feasible and effective one of material incress manufacturing technical.
