摘　　要：圆周分布孔系的加工在生产中比较常见,根据孔系分布的环数、射线数、孔距等的不同,走刀路线的长度不同。在保证质量的条件下,应以最短的走刀路线进行编程加工,以提高加工的效率,降低成本。以沿环形走刀和沿射线走刀两种方式为例,分别建立了走刀路线长度计算的数学模型,编制出能自动选择最短走刀路线进行加工的宏程序,实现对走刀路线及加工程序的优化设计,提高了加工效率。The machining of circumferentially spaced holes is frequently needed in manufacturing. The length of the cutting tool path of a set of holes varies in accordance with its number of rings, its number of rays, the distance between holes, and so on. In order to improve machining efficiency and to reduce cost, without compromising quality, the machining process should be done based on the shortest cutting path. The mathematical models of ring cutting and ray cutting were established, the lengths of their paths were calculated respectively. A macro program in which the shortest paths could be automatically chosen for machining was written. The cutting tool path and the machining program for circumferentially spaced holes were thereby optimized, resulting in improved machining efficiency.
