Optimization of Machining Parameters for Material Removal Rate and Machining Time While Cutting Inconel 600 with Tungsten Carbide Textured Tools M. Adam Khan and Kapil Gupta Abstract Machinability of nickel-based superalloy Inconel 600 was investigated with textured tungsten carbide cutting tool. The cutting tool edges are modified with laser engraving process to produce three different texture patterns on flank face of the tool. Experiments are planned to performed on CNC machine with twenty-seven combinations of input process parameters. Cutting speed (50, 100 and 150 m/min), feed rate (0.08, 0.1 and 0.12 mm/rev), depth of cut (0.1, 0.2 and 0.3 mm) and tool texture (dimple, line and spline) are the input parameter to study the machinability in terms of material removal rate and machining time. To identify the optimal process parameter, three different optimization techniques namely TOPSIS, Grey relational analysis and MOORA have been employed. It has been identified that the maximum cutting speed of 150 m/min at feed rate of 0.12 mm/rev and 0.3 mm depth cut can produce maximum material removal rate of 4268.39 mm3 /min. Moreover, the optimum machining time obtained is 0.259 min. Keywords Machining · MRR · Optimization · Superalloy · TOPSIS · MOORA
2.1 Introduction Nickel-based superalloys are in high demand for many engineering applications due to their superior properties such as metallurgical stability, high strength and temperature resistance, and high corrosion resistance etc. [1, 2]. On the other hand, these alloys are difficult-to-machine by conventional cutting techniques that results in poor machinability in terms of high tool wear, surface quality deterioration, and high consumption or energy and resources etc. [3–6]. Ample research work has been done on machining of superalloys with a wide range of cutting tools and using M. Adam Khan · K.

various optimization techniques for machinability enhancement of various difficultto-machine materials [7–12]. Not only plain tools, but textured tools also have been used to enhance the machinability in recent past. The commonly available tool texture patterns are dimples, holes, grooves and tracks in different angles on tool flank and rake faces [12–14]. There are different techniques followed to make tool texture on the cutting tools. In current research scenario, the tool texturing is made from laser engraving, ion beam texture process, electrochemical processing and wireEDM techniques [12–18]. Laser surface texturing or engraving has high demand and remarkable benefits such as low cost, l
