机床主轴热误差建模

Thermal Error Model for Spindle of Machine Tool

在测量机床关键部件温度和主轴热误差的基础上 ,用逐步回归方法建立了多元线性回归模型 ,并介绍了温度变量的选择。为机床的设计与制造提供了参考依据 。

s:On the basis of testing the temperature of key com- ponents and the thermal error of spindle of machine tool,a multiple regression analysismodel is setup by stepwise regres- sion method.The paper also introduces the selection of tem- perature variables.It offers a reference basis to machine tool design and manufacture and supplies a model for compensating error of machine tool.
