翻译研究了不同因素对进给系统热误差的影响规律。研究了电主轴发热对X向进给系统定位误差测量的影响通过不同进给速率实验揭示了非运动发热、运动发热以及综合发热对进给系统的影响规律证了X向进给系统的热误差由非运动发热和运动发热引起的热误差叠加而来；研究了电主轴发热对Z向进给系统定位误差测量的影响并通过预热实验消除了该影响通过不同进给速率热误差实验获得了进给速率对Z向进给系统热误差的影响规律。

We investigated the influence of different factors on thermal errors in the feed system. The impact of electric spindle heating on the measurement of positioning error in the X-axis feed system was studied, and experiments at different feed rates revealed the influence of non-motion heating, motion heating, and comprehensive heating on the feed system. It was proved that the thermal error of the X-axis feed system is caused by the superposition of thermal errors caused by non-motion heating and motion heating. The impact of electric spindle heating on the measurement of positioning error in the Z-axis feed system was also studied, and the influence was eliminated by preheating experiments. The influence of feed rate on the thermal error of the Z-axis feed system was obtained through thermal error experiments at different feed rates
