It is noteworthy that the AISI 304 stainless steel is characterized by deformation-induced phase transformation of austenite to martensite. Notwithstanding, De et al. [ Citation 33 ] reported that stress–strain curves for temperatures higher than 298 K and low strain rates follow a typical 'parabolic' evolution, which makes possible to model inelastic deformation …
Wet turning AISI 304 round bars and power measurement were performed and are shown in Figure 2. The computer numerical control (CNC) lathe is Yishui CKJ6163 (Yishui Inc., Shandong, China), with a maximum spindle speed of 1000 rev/min, a maximum spindle power of 11 kW, and a cooling pump power of 0.125 kW.
