Thermal Error Test and Intelligent Modeling Research on the Spindle of High Speed CNC Machine Tools

摘要：

　　Thermal error is the main factor affecting the accuracy of precision machining.Through experiments,this paper studies the thermal error test and intelligent modeling for the spindle of vertical high speed CNC machine tools in respect of current research focuses on thermal error of machine tool.Several testing devices for thermal error are designed,of which 7 temperature sensors are used to measure the temperature of machine tool spindle system and 2 displacement sensors are used to detect the thermal error displacement.A thermal error compensation model,which has a good ability in inversion prediction,is established by applying the principal component analysis technology,optimizing the temperature measuring points,extracting the characteristic values closely associated with the thermal error displacement,and using the artificial neural network technology.
