翻译基于对进给系统热误差的产生机理和其影响因素的分析对建模温度点进行了选择利用多元线性回归模型建立了X向进给系统和Z向进给系统的原点漂移误差和热膨胀误差模型在保证模型具有较高预测精度的同时也有较强的鲁棒性。

Based on the analysis of the mechanism and influencing factors of thermal errors in the feed system, the modeling temperature points were selected, and using a multiple linear regression model, the origin drift error and thermal expansion error models for the X-axis and Z-axis feed systems were established. The model ensures high prediction accuracy while also having strong robustness.
