This paper emphatically researched the problem how to calculate the intersection point between workpiece that rotated with variational angle velocity and milling cutter that moved with complicated track and rotated with high speed. furthermore it adopted the discrete curve surface method for every milling cutter, and treated image frame as the control parameter of position of milling cutter during the intersection calculation process, so the algorithm of intersection between workpiece and milling cutter was obtained. the paper also discussed further three - dimension graphic problem of manufacture process
文中對做變角速度運動的工件和運動軌跡復雜的高速自轉中的銑刀求交問題進行了重點研究，採用將銑刀上的每個刀尖劃出的曲面離散化的方法，以圖像顯示的幀數作為求交計算過程的銑刀位置的控制參量，得出了銑刀與工件的求交演算法。 -
