| 摘 要： | 在研究金属切削机床加工误差的基础上,针对机床主轴回转运动误差中的径向跳动误差、角度摆动误差和轴向窜动误差,以车床和镗床主轴为例,建立了主轴回转运动误差数学分析模型,从数学几何角度分别对上述主轴回运动城的加工精度影响结果进行了定量分析,并推导出了由此产生的各类加工几何误差不同的数学表达式。通过这些数学表达式可以定量地计算出机床主轴由于回转运动误差产生的加工几何误差数值。

| Abstract: | Taking lathe and boring machine spindle error motion as an example considering machine spindle radial runout, angular swing and axial shifting, the machining errors of metal cutting machine tools are studied. On the basis of established spindle error motion mathematical analysis model, quantitative fruits of influence on machining precision are analyzed. Mathematical equations for different machining geometrical errors are established. Through the mathematical equations, numerical values of machining geometrical error caused by machine spindle error motion are calculated. |
