Effect of nose radius on forces, and process parameters in hot machining of Inconel 718 using finite element analysis

Effects of cutting parameters on machinability characteristics of Ni-based superalloys: a review

“…This was attributed to decreased chip thickness at trailing edge, which may subject the material to high pressure and high temperatures. Similarly, Parida and Maity [2] found that increased nose radius led to higher effective stresses in cutting region. In the study, tungsten carbide tools with nose radius values of 0.4 mm, 0.8 mm and 1.2 mm were used in turning of Inconel 718.…”

“…In turning of Inconel 718 with multilayer coated carbide inserts, Cantero et al [44] reported a lower cutting force at the speed of 70 m/min than 50 m/min. Parida and Maity [2] reported Figure 9: Effect of cutting speed on cutting force [35] that cutting forces decreased when speed was increased from 40 to 100 m/min in machining of Inconel 718. Ezilarasan et al [10] concluded that a reduction in tangential cutting force was seen with an increase in cutting speed in turning of Nimonic C-263 super alloy.…”

“…Therefore, in machining of the nickel based superalloys, it becomes essential to understand the material removal process and selecting the optimum cutting parameters to meet the desired dimensional accuracy, surface quality and surface integrity of the finished product. Many studies have been carried out towards understanding the optimum cutting parameters of nickel-based superalloys in analytical [8] and simulative approaches [2,[9][10][11][12][13][14][15][16][17][18] as well as experimental [19][20][21][22][23][24][25][26][27][28][29][30][31] studies. In those studies, various cutting process parameters (e.g.…”
