“…It must be noted that, as observed in Table 5 and Figs. 19 and 20, the chipping and delamination wear generate at the cutting speed of 495 m/min. Figure 19 can explain the internal mechanism inducing this phenomenon.…”

In this paper, the in uence of the cutting speed, feed, and the depth of cut on the cutting force, surface roughness, cutting temperature, and tool wear were experimentally investigated under the low temperature oil-on-water (LTOoW) cooling and lubrication condition in turning the hardened tool steel AISI D2 (60±1HRC) with the PCBN cutting tool. The results showed that the three-component cutting forces is F Y >F Z >F X and the cutting speed has more signi cant effect on the ratio of F Y /F Z at the range of 55-495 m/min cutting speed, 0.05-0.25 mm feed, and 0.05-0.25 mm depth of cut. The in uence of the cutting speed on the cutting temperature is slightly more visible compared to the feed and depth of cut. In this experiment, a satisfactory surface roughness value of 0.54 µm can be obtained, gaining the effect of the turning instead of the grinding. The ank wear values of the PCBN tool are 142 µm and 148 µm respectively at the cutting speeds of 55 and 140 m/min; however, the ank wear value abruptly increases to 668 µm at a 495 m/min, which has a very serious impact on the tool life. The abrasive wear is considered to be a predominant wear mechanism on the ank wear of PCBN tool. The rake face is dominated by crater wear due to the high temperature, high pressure, high stress and high friction at the chip-tool interface.

“…The cooling and lubrication technology has been shown to prolong the life of the cutting tool. Moreover, the in uence law and internal mechanism of the nozzle position and diameter on surface roughness and tool wear have been investigated by Yao et al [19] under the condition of OoW droplets cooling and lubrication.…”

“…There are also some related studies on spray cooling. Yao et al [ 13 ] found that increasing the air pressure could reduce the diameter of the spray droplets, enhancing their penetration ability and enabling easier reduction in the tool’s temperature. Under the condition of spray cooling, Ramanuj et al [ 14 ] employed coated carbide cutting inserts to machine AISI D2 steel.…”

To effectively reduce residual stresses in GH4169 workpieces, thus enhancing fatigue strength and operational lifespan, this study investigates the influence of spray cooling parameters on surface residual stresses during GH4169 turning in spray cooling conditions, utilizing both simulation and experimental approaches. A simulation model of residual stresses was established using finite element analysis when GH4169 was cut in spray cooling. The effects of spray pressure and flow rate on residual tensile stresses were analyzed. The analysis reveals that with increasing spray pressure, residual tensile stresses show a decreasing trend, gradually stabilizing. Conversely, with an increasing spray flow rate, residual tensile stresses initially decrease and then increase. The turning experiments of GH4169 were conducted under different spray parameters. After the experiment, the workpiece was sectioned and analyzed for residual stresses using X-ray diffraction instrumentation. The value residual stress measured closely matched those of simulation, with a relative error within 6%, validating the accuracy of the simulation model and confirming the appropriateness of parameter settings. These results contribute to the further promotion of spray cooling technology and facilitate the rational selection of spray parameters.
