前言采用施莱辛格或塞阿蒙等人的方法测量轴的回转精度时,不能很好地反映运动误差。因为机械量仪的响应特性是受速度限制的。而轴承特性,结构振级及振型恰好主要取决于速度。工作的误差也不能完整地反映主轴的运动误差。因为,工件误差还受加工过程中的因素(刀具轨迹的干涉、切削瘤的形成、刀侧面磨损引起的阻尼等)的影响。为此,很多研究者及研究单位提出或讨论一些新方法,希望在示波器的屏幕上得出排除切削过程影响的加工表面形状。最近,ASME 提出一项关于运转精度“(axrs of Rotafion)”的暂 Preface The use of Schlesinger or Seamon et al., When measuring shaft slew accuracy, does not adequately reflect motion errors. Because the response of the mechanical gauge is speed-limited. The bearing characteristics, structure vibration level and vibration mode exactly depends on the speed. The working error can not completely reflect the spindle’s motion error. Because of the workpiece error is also affected by the processing of the factors (tool path interference, the formation of cutting tumor, knife side wear caused by damping, etc.). To this end, many researchers and research institutes put forward or discussed some new methods, hoping to get the shape of the machined surface that excludes the influence of the cutting process on the oscilloscope’s screen. Recently, ASME proposed a temporary “axrs of Rotafion”
