摘　　要：基于多体系统理论,以某种数控铣齿机为例,基于小误差假设,建立了包含34项热误差元素的热误差综合数学模型,并通过数控铣齿机的特殊运动状态和热误差补偿实验验证了热误差综合模型的可靠性。Based on the multi- body system theory and the assumption of small error,it takes a NC milling machine as an example,establishes a synthesis thermal error model which involves 34 error components. It analyzes the special motion state of the machine and the experiment of the thermal error compensation,verifies the reliability of the model.
