摘　　要：运用图形矩阵变换原理和矢量运算法则 ,推导出了立铣刀周铣过程中刀具切削刃上任意点相对于工件运动的轨迹方程 ,在此基础上构造出一种基于工件网格划分的三维表面形貌仿真算法 ,并给出了相应的仿真算例 .仿真结果表明 ,该算法可完全模拟铣削过程 ,具有运算速度快。Using the principles of transformation matrix and vector operation, the trajectory equation of cutting edge relative to workpiece is derived. Based on it, a three-dimensional milled surface topography simulation algorithm is developed through dividing a workpiece into regular grids. Some corresponding simulation examples are given. The results indicate that this algorithm can completely emulate the milling process, and is characterized by high efficiency, high precision and convenience for graphical display.
