Recently, a research team from State Key Laboratory of Mechanical Transmissions, Chongqing University of China has found the coupling relationship between thermal control (TC) process and material removal (MR) process of precision machine tools. The research team believes that the coupling relationship of the two functional processes can affect the machining accuracy and energy efficiency by influencing the thermal balance characteristics and energy characteristics of machine tools. This study can be found in the journal Frontiers of Mechanical Engineering on 29 April, 2022.
