摘　　要：主轴回转误差是影响机床加工精度的重要因素之一,通过构建测试车床的主轴回转误差测试的系统,研究在线条件下主轴回转误差对工件圆度误差的影响关系。研究结果表明,主轴回转误差与工件圆度误差的形态相似度高,而且两者相关性系数在0.9以上。这为后续采用主轴回转误差对精密加工机床的加工工件圆度误差预测提供了研究基础。Spindle rotation error is one of the important factors affecting the machining accuracy of the machine tool,By constructing the system of the spindle rotation error test of the test machine,the influence of the spindle rotation error on the roundness error of the workpiece under the online condition is studied.The research results show that the morphological similarity between the spindle rotation error and the workpiece roundness error is high,and the correlation coefficient between the two is above 0.9.This provides a research basis for the subsequent use of the spindle rotation error to predict the roundness error of the machined workpieces of precision machining machines.
