摘　　要：分析了运动控制芯片MCX3 14的控制原理及单步插补实现过程 ,提出了基于运动控制芯片MCX3 14实现螺纹切削的单步插补控制法 ,从而实现快速、高效的螺纹加工。该方法控制过程简单 ,同步实现锥螺纹 ,控制精度高 (0 .0 0 1mm) ,响应快 (≤ 1.6MHz) ,脉冲确保不丢失 。The control principle and the realization of single step interpolation are analyzed in this paper, and the single step interpolation to realize the thread-cutting based on the motion controller NCX314 is presented. The result is that the high efficiency of thread-cutting is reached. The control process is simple, and it can realize the taper thread-cutting synchronously. Its characters are high control precision and rapid response, no pulse lost. The existing problems of CNC thread-cutting are solved.
