在微型零件的数控加工中，机床的运动精度对加工产品的尺寸质量有很大的影响。轨迹曲线和轴位移速度值对机床定位误差有干扰。在传统的机床定位精度性能测试中没有考虑到这种情况。本文提出了一种基于圆轨迹定位误差监测和预测的微铣床性能评估方法。利用网格编码器监测数据，建立了一种具有实验规划结构的定位误差监测与预测方法。为评估和验证所提出的方法，进行了不同进给速率和圆轨迹半径的试验。
In CNC manufacture of micro components the manufactured product dimensional quality is strongly influenced by the machine tool movements accuracy. Trajectory curves and axis displacement speed values interfere in the machine positioning error. This situation is not considered in the traditional tests of a machine tool positioning accuracy performance. In this work micromilling machine performance assessment is proposed by means of monitoring and forecasting of positioning errors during a circular trajectory. Data monitored by grid encoder were used for drafting a method structured with experimental planning for monitoring and forecasting positioning errors. Trials with different feed rate and radius for a circular trajectory were carried out for assessment and validation of the method proposed.
