Abstract
Thermal issues constitute one of the primary factors affecting the machining accuracy of CNC machine tools, with temperature fluctuations being a critical element in controlling machine tool errors. In this study, a specific type of CNC machine tool was chosen as the research subject. A comprehensive analysis of the heat generated by each heat source during the machine tool's operation was conducted. A temperature field test was performed, accompanied by a corresponding transient finite element simulation, covering an 8-h machine tool operation period. When comparing the simulation results with the test findings, it was observed that the temperature field error in the simulation was within 5%. This leads to the conclusion that the transient temperature field numerical simulation method presented in this paper can accurately predict the actual temperature field of the machine tool. This, in turn, establishes a robust foundation for subsequent analyses of thermal error compensation in the machine tool.
