In this paper, textured cutting tool was used for machining nickel-based superalloy Inconel 600. A finite element analysis (FEA) to study the machining behaviour of nickel while cutting with textured tools was conducted. The tool rake face was textured with dimple pattern at a gap of 150 µm from the cutting edge. The force exerted from experimental study was used as an input boundary conditions and the simulated with respect to time. From the analysis the principal stress, normal strain and deformation of the tool have been studied using contours plot and its range. It has been confirmed that, the rate of stress and strain found gradual at the beginning and it varied due to the friction and work-tool material behavior. The inference is made to justify the deformation with original worn tool edge and it is confirmed that the tool is qualified to machine hard nickel alloy. The results can also be studied by varying the input parameters.
