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

Abstract

There has been increased awareness of the need to reduce environmental impacts in the last 10 years. The manufacturing industry is striving to reduce environmental impacts by introducing new materials with better characteristics, that consume less processing power and use smaller amounts of processing coolant. The main objective of this paper is to study the effect of the Ranque-Hilsch vortex cooling tube on power consumption and surface roughness quality in the turning process when machining mild steel material with a coated carbide cutting tool. The machining parameters involved in the experiment are cutting speed, feed rate and depth of cut. The cutting speed is fixed at 160 m/min while the feed rate and the depth of cut are varied. The feed rates used are 0.10, 0.18 and 0.28 mm/rev, while the depth of cut is varied from 1.0 to 4.0 mm. During the machining process, the cutting temperatures are measured using an infrared thermometer and the power consumption is measured using a Prova 6830 power and harmonics analyzer. The surface roughnesses of the machined parts are measured using a surface roughness tester. The results show that cooling using Ranque-Hilsch vortex tube air cooling reduces the cutting temperature, but the power consumption and surface roughness are better under ambient conditions except at 0.28 mm/rev feed rate.

“…Ancak Ekinović ve arkadaşları, ıslah çeliklerinde 60 m/dk kesme hızı, 0.098 mm/dev ilerleme, 0.5 mm kesme derinliği ile kuru kesme ve geleneksel soğutucu kullanımının, vorteks tüpü kullanımına göre kesme kuvvetlerine daha olumlu etki sağladığını belirtmişlerdir [33]. Ayrıca A36 alaşımının 160 m/dk sabit hızla ve değişken ilerleme ve kesme derinliklerinde tornalanmasında vorteks tüpü kullanımının, kuru kesmeye göre kesme sıcaklıklarını azaltırken güç tüketimini ve yüzey pürüzlülüğünü arttırdığını gözlemlemişlerdir [41]. Naumov ve arkadaşları, vorteks tüp ile soğutma ve yağlamanın aynı anda yapıldığı sistemlerin, yapı çeliğinde kesme işleminin temel özelliklerinin iyileştirilmesine ve takım ömrüne katkıda bulunduğunu belirtmişlerdir [37].…”

Improving Surface Roughness of Burnished Components using Abrasive Particles

“…The feed rate in turning process has a significant effect on surface roughness and power consumption. At higher feed rates the surface roughens increases affecting the quality of the components [18,19]. Authors have not found much work related to roller burnishing effect on surface roughness and microhardness in different conditions.…”

Multi-Criteria Optimization of Turning of Martensitic Stainless Steel for Sustainability

“…Ginting et al [9] stated that the replacement of wet machining with RHVT cooling can save 80 cents apiece. Taha et al [10] studied the effect of RHVT cooling on surface roughness and power consumption in dry turning. The results showed that this cooling solution reduces the cutting temperature.…”
