In CFRP machining, the friction at the cutting tool/material interface generates significant heat and the machining temperature is loosely related to the formation of surface damage, negatively impacting the cutting tool's performance and reliability . In CFRP machining, the cutting temperature can be influenced by various factors, such as cutting parameters, CFRP material composition, fibre cutting orientation etc. For instance, An et al. observed the machining temperature in orthogonal cutting of CFRP is closely related to fibre cutting orientations, initially increasing then decreasing with fibre cutting orientations, exhibiting a nonlinear trend. Ge et al. found that the drilling temperature decreased non-linearly with feed rate and it first increased then decreased with spindle speed. Additionally, the drilling temperature of CF/PEKK was ∼100 ℃ higher than CF/epoxy, highlighting the significant impact of CFRP material composition on drilling temperature. In CFRP grinding, the machining temperature was significantly affected by the depth of cut, fibre cutting orientation and the use of coolant, with temperature variation displaying high non-linearity . In CFRP milling, the machining temperature increased with feed rate and cutting speed .
