In this work, currently used non-biodegradable mineral oil as a cutting fluid during machining is replaced with vegetable oil. In this work, duplex stainless steel is machined (turned) with the vegetable oils like coconut oil and neem oil. As a first step, vegetable oil based oil-in-water nano-emulsions were formulated using non-ionic surfactant (Tween-80) by ultrasonic emulsification method. In the second step, spindle speed, feed rate, depth of cut and type of cutting fluid are varied at three levels and Taguchi L27 machining experiments were performed. Measurement of surface roughness, tool wear and tool temperature were done as an output performance measure. From the results, it is evident that the order of influence for the improvement of tool wear and surface roughness are cutting fluid, feed rate and depth of cut respectively. © 2017 Elsevier Ltd.

Improvement of Machinability Using Eco-Friendly Cutting Oil in Turning Duplex Stainless Steel

Objectives: The present study investigated the parametric investigation of machinability parameters on the quality characteristics of force (Fz) and roughness (Ra) during the dry turning of Inconel 718 alloy. Methods/Statistical Analysis: Machinability experiments are carried out with PVD coated carbide with (KC5510) and without wiper (KC5525) insert at three speeds (60, 80, 100 m/min), two feed (0.06 and 0.10 mm/rev) and three cutting depth (0.4, 0.8, 1.2 mm) under dry cutting conditions. The experiments are planned based on Taguchi's L18 orthogonal array. The percentage contribution of the machinability parameters on quality characteristics is determined using analysis of variance test (ANOVA). Predictive regression equations are developed for the estimation of all the quality characteristics. Findings: From the experimental results, the most significant factor in case of both Fz and Ra is cutting depth during the turning of 718 Inconel alloy for both the inserts. The Pearson correlation (r) is evaluated whether the correlation is exists between the machinability parameters (speed; feed and cutting depth) on force and roughness. The results of calculated 'r' show that the cutting depth has a strong correlation with both quality characteristic trailed by the speed. Application/Improvements: In addition, the lower magnitude of Ra roughness is observed for KC5010 compared to insert designated with KC5525.
