一、引言主轴回转精度分析历来是精密圆柱零件加工与测试技术中的重要研究课题。以往在加工设备与量仪的设计与制造上,对影响主轴回转精度的诸因素:轴系零件几何精度、装配精度、工作条件、结构形式等,作了多方面改善和提高。近年来又多致力于分离主轴回转误差的测试技术研究,如多位法、反向法、或两者的复合应用等,以及通过精确检测主轴回转误 I. INTRODUCTION Spindle rotation accuracy analysis has always been an important research topic in the machining and testing of precision cylindrical parts. In the past in the processing equipment and measuring instrument design and manufacturing, the impact on the spindle rotation accuracy of the various factors: shaft geometry accuracy, assembly accuracy, working conditions, structural forms, made many improvements and improvements. In recent years, more and more committed to the separation of spindle rotation error test technology research, such as multi-bit method, reverse method, or a combination of the two applications, as well as by accurately detecting the spindle rotation error
