摘　　要：提出了一种自适应变间距直线拟合非圆弧曲线算法。该方法利用数控系统自身宏程序功能,根据非圆弧曲线的曲率变化,在最大误差小于允许偏差条件下,快速自动确定直线拟合曲线的最佳节点,可保证加工精度和加工效率的统一。给出了具体算法流程和实例程序验证,是实际应用中非圆弧曲线加工的有效拟合方法。The algorithm of adaptive variable spacing for line fitting non-circular curve was provided. It can automatically determine the best node for guaranteeing the processing accuracy and efficiency in accordance with the allowable error and the curvature change. Without any other auxiliary software, it can direct programming with NC system macro function. The algorithm procedure and an example of program verification were given. It is one of effective fitting non-circular curve method with line.
