RESEARCH ON OPTIMIZATION OF TEMPERATURE SENSITIVE POINTS OF MACHINE TOOL THERMAL ERROR BASED ON INDEPENDENT VARIABLE SELECTION CRITERIA

Research on optimization of temperature sensitive points of machine tool thermal error based on independent variable selection criteria

Abstract In order to improve the prediction accuracy and robustness of the machine tool thermal error model, a method to select temperature sensitive points of the machine tool thermal error model based on independent variable selection criteria is proposed.Firstly, the positioning error of the machine tool is divided into geometric positioning err
