This study proposes a dynamic active temperature control method for precision machine tools based on structure specific heat dissipation and power generation ratio matching. A thermal control strategy combining thermal accumulation effect with optimized cooling parameters was developed using a precision vertical coordinate machine tool as the research platform. This method determines the optimal heat dissipation rate of different structural components of precision vertical coordinate machine tools (spindle bearings: 60–80%, motors: 30–40%, feed systems: 40–60%) under various working conditions, and achieves dynamic cooling power adjustment. Experimental verification shows that the temperature of the spindle motor decreased by 7.8 °C, and the perpendicularity errors of the XY and ZX planes decreased by 80 and 22%, respectively, verifying the effectiveness of the proposed method.

摘要

This study proposes a dynamic active temperature control method for precision machine tools based on structure specific heat dissipation and power generation ratio matching. A thermal control strategy combining thermal accumulation effect with optimized cooling parameters was developed using a precision vertical coordinate machine tool as the research platform. This method determines the optimal heat dissipation rate of different structural components of precision vertical coordinate machine tools (spindle bearings: 60–80%, motors: 30–40%, feed systems: 40–60%) under various working conditions, and achieves dynamic cooling power adjustment. Experimental verification shows that the temperature of the spindle motor decreased by 7.8 °C, and the perpendicularity errors of the XY and ZX planes decreased by 80 and 22%, respectively, verifying the effectiveness of the proposed method.
