摘　　要：为满足数控系统的高速度、高精度、高效率和高可靠性,本数控系统采用了快速插补运算技术,以提高直线、圆弧插补运算性能,实现复杂曲面零件微小区段的逼近,并在插补前采用加减速控制,使加工轮廓误差减至最小。The fast interpolation operation technology is adopted in this CNC system to satisfy the high speed, high precision, high efficiency and high reliability of CNC system. The line and arc interpolation operation function can be improved and the tiny section of complex curve part can be approached by this technology. The speed-up and speed-down control is adopted before the interpolation in this CNC system in order to minimize the error of machining outline.
