在当今所使用的主流数控系统中,都对圆弧过象限插补计算的算法进行了很大的改进,尤其是现在的国外先进的数控系统已经可以很好地解决这个问题,能够实现一次完成整圆的程序编制,并广泛在中小件铣削加工中得到了很好的应用,但是在大件加工领域却依然存在不少问题。本文就此类问题提出解决的办法。 In today’s mainstream CNC system, arc quadrant interpolation algorithm has been greatly improved, in particular, the current foreign advanced numerical control system can already be a good solution to this problem, to achieve a complete Whole-round programming, and widely used in small and medium-sized pieces of milling has been very good application, but there are still many problems in the field of large-scale processing. This article puts forward solutions to such problems.
