An experimental investigation of oil jet lubrication effects at various injection angles, cutting parameters, and pressure on surface roughness in different-speed machinery

<ns3:p>This study investigates oil jet lubrication’s effects in different-speed machining, testing injection angles (15 and 40) and pressures (6–12 bar) on surface roughness and wear.We can achieve these goals by performing the oil jet lubrication used throughout the turning process, with two different injection angles (15 and 40) included in the lubrication conditions.Results show optimal performance at 15 and 6 bar, reducing roughness and temperature. The findings aid in selecting lubrication parameters for improved machining efficiency. One of the more significant findings from this study is that at 40 and 6 bar of pressure, the cutting speed ranges from 48 to 264 meters per minute, with the highest temperature reaching 134%. In contrast, under 15 and 6 bar, the highest temperature is 118%.We suggest that you carry out a quality surface, it is necessary to experiment with the cutting speed that significantly impacts the tools’ and workpiece’s wear and surface roughness. As the workpiece undergoes more plastic deformation at a higher cutting speed, a greater amount of mechanical energy is converted into heat energy, resulting in a notable increase in temperature. Low-carbon steel and various cutting tools were used in the studies.The effect of variables studied was cutting speeds (48, 88, 180, 264) m/min, feed rates (0.03, 0.043, 0.075) mm/rev, depths of cut (1) mm, and injection angles (15 and 40). Lubrication pressures ranged from 6 bar to 12 bar. No one has certainly facilitated improvements in the tribological properties of (AL-Rashid Oil) SAE 15W_40 through Oil jet lubrication, which was used throughout the turning process, with two different injection angles (15 and 40) included in the lubrication conditions.</ns3:p>
