The Effect of Vortex Tube Air Cooling on Surface Roughness and Power Consumption in Dry Turning

Article Preview

Abstract:

This paper presents a study of the effect of Ranque-Hilsch vortex tube air cooling on surface roughness quality and power consumption when turning mild steel material with coated carbide cutting tool. The cutting parameters involved in this study were cutting speed, feed rate and depth of cut. The cutting speed and feed rate were fixed at 160 m/min and 0.28 mm/rev, while the depth of cut was varied from 1.0 to 4.0 mm. During the turning process, the cutting temperatures were measured using an infrared thermometer and the power consumption was measured using a power and harmonics analyzer. The machined parts surface roughnesses were measured using a surface roughness tester. The results show that cooling using the Ranque-Hilsch vortex tube air cooling reduces the cutting temperature and the power consumption, but the surface roughness results is better when cooling with environment air.
