摘要
复杂型胶类零件的加工是数控编程中的一个难点.本文从提高加工算法的稳定性和加工效率的角度出发.提出了一个复杂平面型腔数控加工的优化算法.即通过二维环的等距、自交、集合等基本运算.按“端点同环最短距离优先剖面线算法”规划并优化刀具轨迹.最后给出了应用实例.
This paper is the statement of goals guidelines and procedures to automate the generation of an optimized ordering of 2-D tool paths for 2. 5D axis milling of arbitrary pockets for molds and dies designed on a geometric modeler. It addresses the overall goal of increasing productivity by shortening manufacturing time. The tool retraction has to be reduced to the minimal number possible.
