本文的目的是利用具有时滞的传递函数来估计机床模型的热变形。根据切削区相对位移与指定表面温度之间的传递函数,建立了基于频域的热变形预测方法。利用机床模型中热源附近的两个指定表面温度,预测切削区域的相对位移。结果,该方法可以足够确定地预测在机器的启动瞬态行为上温度以什么速率变化最快。本文提出的方法对估算热变形是非常有效的,并证实了实验值与估算值之间的误差将显著减小。
The purpose of this paper is to estimate thermal deformation of machine tool model by using transfer function with time delay. The prediction method of thermal deformation based on frequency domain is constructed from transfer function between specified surface temperatures and the relative displacement in cutting area. The relative displacement in cutting area is predicted using two specified surface temperatures near heat source in machine tool model. As a result, the method can be predicted with enough certainty at what rate the temperature changes the most rapidly on machine's startup transient behavior. The method proposed in this paper is remarkably effective to estimate thermal deformation and confirm that the error between experimental and estimated values will be remarkably reduced.
