T.T.M Kannan et al. [2014] performed the experiment on AISI 316 Austenite stainless steel to investigate the heat partition, tool wear and tool life. In their investigation they found that
CBN cutting inserts has been damaged in moderate cutting velocity and produce good machinability and higher cutting temperature decreases the yield strength of produced white layer. [11]
R.Suresh et al. [2014] studied the effect of various cutting parameters in hard turning of
AISI H13 steel at 55 HRC with Poly vapour deposit (PVD) coated TiCN ceramic tool under dry cutting conditions. They used Central composition design concept of Response surface methodology for design of experiments and concluded that abrasion was the principal wear mechanism observed …show more content…
[2014] investigated the effects of varying speed and feed rate on AISI
D2 steel at 62HRC and to determine the resultant forces. They use Finite element simulation
(FEM) to investigate the chip removal theoretically and then compare the results with practical results. It can be stated that the passive force is the most dominant force component and theoretical cutting force values are 45-120% higher than the measured one. [13]
D.K Das et al. [2014] investigates the surface roughness during hard turning of EN24 of 50
HRC hardness with coated carbide insert. By using grey based Taguchi and regression analysis it was concluded that surface roughness of 0.42 micron is obtained at cutting speed of 130 m/min, depth of cut 0.4 mm/rev and feed rate was found to be most dominant parameters for output response. [14]
A.K Sahoo et al. [2014] studied the performance of multilayer carbide insert in the machining of AISI D2 steel at 53 HRC using Taguchi L27 orthogonal array to predict surface roughness also S/N ratio and optimum parametric condition were analysed. He found that feed is most influencing parameter for surface roughness followed by cutting speed whereas depth of cut has least significance on surface response. …show more content…
AISI 4140 hardened alloy steel at 56 HRC is used and machined with PVD coated ceramic insert. They concluded that higher the work material hardness the higher is the machining force. It is found out that for turning of AISI 4140 steel optimal cutting parameters are cutting speed of 180 m/min, feed rate of 0.08 mm/rev, cut of depth of 0.15 mm and gives surface roughness of Ra= 0.23 micron.

S.Chinchanikar et al. [2015] investigated the effect of minimum quantity lubrication (MQL) on hard turning of AISI 4340 steel at 55 HRC using TiSiN-AiAlN coated carbide tool. By multi objection optimization of parameter in dry and MQL cutting conditions it is observed that hard turning under MQL produce a significant improvement in tool life by almost 30% I comparison to dry cutting and also lowering cutting forces and surface roughness. Optimum cutting conditions of cutting speed= 136 m/min, feed rate= 0.088 mm/rev, depth of cut= 0.3 mm were observed. [17]
P.Netake et al. [2015] developed a statistical model to predict the cutting force and surface roughness during hard turning of AISI 52100 alloy steel at 62 HRC under minimum quantity lubrication using PVD coated nanocrystalling TiSiN-AiAlN coated carbide tool. It was
