摘　　要：提出一种简化的数控车削加工步长计算方法,根据曲线在坐标轴的2个方向的变化量比值来确定步长的大小,在车削循环中应用变步长方法,使数控系统运算效率和加工精度提高。A simple method which can calculate processing step in CNC turning was proposed. According to the ratio of variation in both directions, the step size was determined. By using processing methods of variable step in turning cycle, NC system operation is more efficient and machining accuracy is higher.
