Effect of Minimum Quantity Lubrication during Machining of Incoloy 800H Using Vegetable Oil Enriched With Nano Particles

In this experimental work an effort has made to investigate the machining of difficult to machine Incoloy 800H super alloy. Cryogenically treated textured cutting inserts and vegetable oil enriched with nano particles were used for this study. The turning experiments were performed with different parameters such as Cutting speed, feed rate and depth of cut. Surface Roughness, Cutting Force, Tool-Tip Temperature and Power were the output responses considered. Grey Relational Analysis (GRA) and Analysis of Variance (ANOVA) analysis were used to optimize the machining parameters and to find the most influencing machining parameter on the output responses. The results showed that the optimal machining conditions considered were cutting speed at 35 m/min, feed rate at 0.06 mm/rev and depth of cut at 0.5 mm for the multiple-characteristic performances and it was improved by 3.86 % with this approached method. Also, Tool-tip temperature and Power were reduced during machining with cryo treated textured inserts. Laser textured-cryogenically treated cutting insert’s hardness was increased when compared with conventional inserts. Moreover, the results revealed that nanoparticles enriched base fluid gives better performances in terms of surface roughness, tool wear and cutting force.
