Conceptual NC Grinding Wheel Dressing Based on NURBS

在分析计算 NU RBS曲面单位法矢量的基础上 ,提出 NC磨床加工系统方案创新设计方法 ,采用平移、旋转和固定等概念模块 ,准确地表达 NC磨床运动模型 ,采用链表结构表达 NC磨床的运动设计方案 ,采用

A NC preliminary design paradigm is put forward through analyzing and calculating the normal unit vector of the NURBS surface. By exploiting typical modules, such as the translating module, the rotating module and the base module, the NC movement conceptual configuration is precisely expressed. This conceptual module is recorded in the computer. By the introduction of agent, the creative preliminary design is realized and the interpolation control technique is completed in the course of grinding wheel dressing.
