摘　　要：为了在加工误差允许范围内的情况下,实现轨迹连续加工和保证拐角处的精度,进而使得数控机床的总体加工精度得到有效的提高。在微小线段连续插补算法的基础上进行改进,提出了一种新的插补算法。通过采用"虚三角插补"的方式,在不损失拐点精度的情况下,不仅保证加工速度的连续性,而且大幅度提高加工精度,所提出的高精度微线段插补算法对高性能数控机床的研制具有一定的参考价值。In order to ensure processing errors are allowed within the scope of circumstances,to achieve trajectory continuous process and to ensure the accuracy of corner making the overall precision CNC machine tools increased.So a new interpolation algorithm was proposed on the basis of algorithm for micro-line continuous interpolation.The basic idea of the algorithm was an approach about ＂virtual triangle interpolation＂,in the case without loss of precision turning point,not only to ensure continuity of processing speed,but also greatly improve the processing accuracy,theory suggests high-precision micro-line interpolation algorithm for high-precision CNC machine tool research has some value.
