Metal cutting or machining is a backbone of manufacturing industries. In machining process, heat is generated and it must be removed with the help of cutting fluid. Generally, hydrocarbon oil based cutting fluid is used, but it leads to environmental pollution and as well as operator’s ill health. Solid lubrication is a good alternative to hydro carbon oil based cutting fluid.In this work, turning process is carried out on Inconel 718 with perpendicular direction textured cutting insert filled with different solid lubricants.Solid lubricants as lubricant materials, which are basically solid but becomesoft due to frictional heat at the point of contact. In this work, Molybdenum disulfide (MoS2) and Graphite solid lubricants are used.Experiments are performed as per L9 orthogonal array and theeffect of each process parameter is determined through the Analysis of Variance (ANOVA). The result revealed that solid lubricant with textured tool produces a continuous lubricating layer on the surface of the tool due to the thermal expansion of heat produced during machining. This thin layer may reduce friction in the machining zone. Perpendicular direction textured cutting inserts are used to reduce friction and good surface finish is obtained.Compared with MoS2, graphite has shown better results in terms of surface finishdue to its low shear strength properties.
