回归正交设计在机床热误差建模中的应用

在对现有机床热误差建模方法分析基础上，提出回归正交设计建模法，并给出比较详细的计算和分析过程．该方法以统计理论为基础，结合机床机构、环境条件、工程判断、众多经验等因素综合起来进行热误差建模，避免了现有建模方法完全依赖建模数据，从而使建立出来的热误差数学模型的鲁棒性更强、实际应用效果更好．

Based on analyzing the existing approaches of the thermal error modeling for machine tools, a new approach of regression orthogonal design is proposed, which combines the statistic theory with machine structures, surrounding condition, engineering judgements, experiences in modeling. Therefore, the models got from this method are more robust and practical than those got from the present method which depends on the modeling data completely.
