为了对丝杠热变形误差进行实时控制 ,在丝杠尾部安装传感器实时测量丝杠的热伸长值 ,利用神经网络建立了该伸长值与丝杠螺距补偿值之间的关系 ,从而消除了热伸长引起的非线性丝杠螺距误差 .
In order to control the thermal deformation error of the screw in real time, the thermal elongation value of the screw is measured in real time by installing the sensor in the tail of the screw. The relationship between the elongation value and the screw pitch compensation value is established by the neural network, Nonlinear lead screw pitch error due to thermal elongation.
