摘　　要：以实验室自行开发的双转台五轴数控机床为研究对象,利用研制的温度和热误差检测系统测量了双转台五轴机床的温度场和热误差。基于相关分析原理,确立了建模和补偿用的最优敏感热源点。利用MATLAB建立了该机床的多元线性回归分析热误差模型。实验表明,补偿后机床热误差平均减小了40%。The research identified the temperature fields of a two turntable 5--axis machine tool by placing temperature sensors, and measured the spindle thermal errors in three directions by displacement sensors. The correlation analysis theory was used to find the correlation between temperature data and thermal error, and multiple variable regression linear method was used for establishing thermal error model. The experiments proved that there is averagely a 40% decreases in machine tool errors.
