摘要
为了解决基于三维模型的机加工艺设计中工序模型的建立问题,提出了基于布尔运算的轻量化模型建立方法。通过对轻量化模型格式的分析,建立了轻量化模型的数据结构,在此基础上对轻量化模型的建立方法进行了深入地研究,给出了模型建立的实现过程并对其中涉及的相交测试及交点计算、点及面的重组算法进行了详细的讨论。最后,通过建模实例对该算法进行了验证。
To solve the modeling of In-process Work Piece in three-dimensional model-based mechanical machining process planning system,a method of modeling technology for Lightweight Model based on Boolean operation was brought forward.By analyzing the format of the lightweight model,the data structure of it was constructed,furthermore,the modeling technology of lightweight model was studied,and the key technologies in the generation of model including intersection test and calculation,points and surfaces reorganization were discussed in detail.In the end,this method was validated through a case.
