An Experimental Investigations in Turning of Incoloy 800 in Dry, MQL and Flood Cooling Conditions

The current research involves the performance analysis in turning Incoloy 800 in dry, minimum quantity lubrication (MQL) and flooded cutting scenario. Two types of MQL namely MQL1 (150 ml/h) and MQL2 (230 ml/h) have been implemented. Flooded cooling rate has been fixed as 600 ml/h. Low budget uncoated tungsten carbide tool of ISO designation CNMG 120408 tool is utilized to accomplish the turning experiments. Grey relational method is used to ameliorate the cutting process restrictions (feed, cutting-speed, and depth of cut), in order to have minimum roughness of surface and tool flank wear. Later analysis of variance (ANOVA) is carried out to analyze the impact of turning variables on responses. The outcomes obtained show that the roughness of surface and the tool wear both are minimal under MQL conditions whereas performance under MQL2 is more favorable than MQL1.
