| 摘 要： | 提出了一种采用运动学中空间位移的方法,基于可变形NURBS(D-NURBS)自由曲线构造数控加工中刀具扫描体曲面的CAD模型,使原来的几何曲线曲面具有物理曲面的特性,这样就允许设计人员以自然的、可预测的方法运用许多基于力的工具进行交互式造型,直接设计型面.所得曲面易满足所使用的特殊的数控加工机床的运动和动力学限制,同时得到了自由曲面数控加工的刀具路径设计的新方法,该方法将运动学、计算机辅助几何设计与CAD/CAM技术结合起来,为并行几何形状设计和制造提供了基础.

| Abstract: | Based on deformable NURBS(D-NURBS)free-formed curve, a kind of space displacement method in kinematics is used to construct the CAD model of tool sweeping body in NC machining. Then the primary geometry curve and surface are provided with the characteristics of physical surface. In this way, it is allowed that the designer can exert many tools based on force with the natural and dividable method to sculpt interactively and design the surface directly. Therefore, the surface can satisfy the kinematics and mechanics limit in the special NC machine easily. At the same time, the new method to design the NC machining tool path of free-formed surface. The technology of kinematics, CAGD and CAD/CAM are integrated in this method, and provide the base for synchronism shape design and manufacture. |
