Coupling evaluation for material removal and thermal control on precision milling machine tools

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 1,   Pages 12-12 doi: 10.1007/s11465-021-0668-9

Abstract: material removal (MR) energy as useful energy consumption and ignored the useful energy consumed by thermalcontrol (TC) for maintaining internal thermal stability and machining accuracy.Hence, the cutting energy efficiency model considering the coupling relationship is established basedThe forced cooling mode of TC results in a 7% reduction in cutting energy efficiency.This paper reveals the coupling effect of MR and TC on energy efficiency and machining accuracy.
