Effect of Near-Dry Machining (NDM) on surface roughness through sustainable turning of mild carbon steel using coated carbide

Abstract

Abstract Sustainable production as a global word, content important elements on all the fields as well as machining processes. Turning is one of the most fundamental and indispensable processes of metal removal in the industry. Increasing pollution preventing initiatives globally and consumer focus on environmentally conscious products has put increased pressure on industries to minimize or eliminate the use of cutting fluids. The use of Near-Dry Machining (NDM) in machining operation is one of the most effective strategies in this direction to achieve sustainable machining system. This study was purposed to determine the influence of NDM coolant system on surface roughness when turning of mild carbon steel, include power demand. A detailed comparison has been made with dry cutting to assess the process performance on the basis of surface roughness and power demand. The results indicate that providing a reduction on surface roughness and power demand more effectively than dry cutting at high-speed conditions, thereby to achieve sustainable machining system.
