标准范围

本文件提供了确定数控机床轮廓性能的方法。本文件规定了测试和评估双向圆误差、平均双向径向误差、圆误差和由两个线性轴同时运动产生的圆路径的径向误差的方法。本文件还规定了同时控制（协调）线性轴和旋转轴组合产生的圆形或恒定半径轨迹偏差的测试方法。这些测试的基本原理是协调多个运动轴（旋转轴和线性轴的组合），以保持刀具和工件之间的相对位置不变。本文件描述了圆误差和径向误差之间的差异（附录A），典型机床误差对两个线性轴执行的圆路径的影响（附录B），试验装置的注意事项-带旋转轴的圆形试验的ups（附录C），圆形试验的直径和轮廓速度调整示例（附录D），以及使用反馈信号的圆形试验（附录E）。

This document provides methods for the determination of the contouring performance of numerically controlled machine tools.This document specifies methods of testing and evaluating the bi-directional circular error, the mean bi-directional radial error, the circular error and the radial error of circular paths that are produced by the simultaneous movements of two linear axes.This document also specifies methods of testing the deviations of the circular or constant radius trajectories generated by any combination of simultaneously controlled (coordinated) linear and rotary axes. The basic principle of these tests is to coordinate the multiple axes of motion (combination of rotary and linear axes) to keep the relative position between the tool and the workpiece constant.This document describes differences between circular errors and radial errors (Annex A), influences of typical machine errors on circular paths executed with two linear axes (Annex B), precautions for test set-ups for circular tests with rotary axes (Annex C), an example of adjustment of diameter and contouring speed for circular tests (Annex D), and circular tests using feedback signal (Annex E).
