虚拟加工环境中的工件动态建模方法研究

Dynamic Modeling of Machinable Workpiece in the Virtual Manufacturing Environment

  • 摘要: 提出并实现了基于平面纹理映射的基元立方体构造方法,以之为动态结点建立了动态八叉树结构,实现了支持变精度动态建模的自相似递归算法。该算法确保离正在加工的部位更近的区域有更高的精度,并采用C++Builder和OpenGL构造了一个集成于虚拟加工环境的可加工工件模型。

     

    Abstract: This paper proposes a novel dynamic octree structure to overcome the difficulty of the machinable workpiece modeling that virtual manufacturing is facing.First,The elementary geometry unit constructed with projected planes,which is used to construct the dynamic octree structure,is represented.Second,the self-similitude recursion algorithm is represented to realize a dynamic model with variable levels of detail,namely,there is a higher level of detail where is closer to the part of being machined.Finally,a model of machinable workpiece integrated into a virtual manufacturing environment is constructed,which is coded in C++ Builder and OpenGL.
