“…It may find out the good relationship among various parameters like cutting pace, feed, depth of cut and tool nose radius, etc. with surface trait values [23]. From the analyses of ANOVA, it has been concluded that feed is the most significant factor for machined surface roughness (70.22%) followed by cutting speed (21.93%) and depth of cutting (6.21%) [24].…”

“…In hard turning, PCBN is also the best tool material because of its high degree of thermal stability, high level of wear resistance and great hardness characteristics [7]. Nose radius plays a vital role in obtaining a better surface roughness than other parameters, for example, cutting pace, axial feed rate and depth of cutting [23]. The superior quality of the workpiece surface was identified by the use of CBN (TiN-coated) tools, compared with CBN uncoated tools, in dry conditions of hard turning.…”

Turning of hardened AISI 4340 steel is regarded as one of the demanding challenges in machining sectors where precision tolerances are essential for automobile parts. The AISI 4340 steel is broadly utilized in forged steel automotive crankshafts systems, hydraulic forged and additional machine tool purposes because of their improved characteristics. Moreover, one of the keys confronts in the machining of hard 4340 steel is the comparatively deprived machining behavior that reduces the functionality of the material and further leads to component rejection at the final inspection stage. In addition, accelerated tool wear necessitates for repeated changing of cutting tool that results in higher machining and tooling costs. This comprehensive review aimed to present in-depth features on the development of machining performances using various cutting tools. This review focus is to provide a broad perceptive of the role of controllable variables during machining of hardened steel. This review analysis examines the response variables and their advantages of chip morphology and heat generation. The comprehensive overview of machining settings, key machinability indicators and statistical analysis for AISI 4340 steel. This overview will provide academic, industrial and scientific communities with benefits and shortcomings through improved conceptual understanding towards further research and development.

“…Technological advances have enabled companies to manufacture products with superior quality rapidly, which, in turn, has allowed engineers to adapt different methods for performing several tests to maintain the same surface quality of manufactured products, 1 mainly in hard-turning process that requires fewer operations when compared to the grinding process, saving time and energy. 2,3 Hard turning has several advantages over the grinding process, especially in the machining of complex profiles and in addition, induces compressive residual stresses in the workpiece as opposed to tensile residual stresses induced by the grinding process, which increases the lifespan of the workpiece. Kumar et al 4 listed the main products that have been manufactured by this process, which include automotive gears, axes, inner and outer race bearing.…”

This study focused on determining the residual stress of SAE 52100 hard-turned steel. The objective was to evaluate and compare the effects of the cutting-edge geometry and cutting parameters (cutting speed, feed rate, and cutting depth) on the residual stresses of three different conventional inserts: S-WNGA08 0408S01020A 7025, T-WNGA08 0408T01020A 7025, and S-WNGA432S0330A 7025. Tests were performed on 60 samples of SAE 52100 hardened steel with an average hardness of 58.5 HRC. The circumferential residual stresses of the samples were measured by X-ray diffraction. A full factorial design of experiments with three factors and two levels each with two central points and a replicate was used for a statistical analysis. The most significant results were as follows: For all inserts, the measured residual stresses were compressive, which extended the tool lifespan. The residual stresses of the Type-S inserts were significantly influenced by the cutting speed and depth, and those of the Type-T insert were significantly influenced by the feed rate and cutting depth. In addition, the residual stresses of the insert 3 were more compressive than those of the other two types of inserts. In other words, residual stresses are more compressive for inserts with larger chamfer angles even as the principal residual stress profiles were all compressive. This work has also shown that it is possible to determine a significant statistical relationship between cutting forces and residual stresses, allowing force measurements to predict the residual stress without any information on process parameters.

“…The achievement of high quality, in terms of workpiece dimensional accuracy, surface finish, high production rate, less wear on the cutting tools, economy of machining in terms of cost-saving and to increase the performance of the product with reduced environmental impact are the main and effective challenges of modern metal cutting and machining industries (Sharma et al, 2016;Selvam et al, 2016;Krolczyk et al, 2017). Traditionally, hardened steels are machined by grinding processes due to their high strength and wear resistance properties but grinding operations are time-consuming and limited to the range of geometries to be produced (Zhang and Liu, 2017; Khan and Bhivsane, 2018). In recent years, machining the hardened steel in turning which uses a single-point cutting tool has replaced grinding to some extent for such application (Mia and Dhar, 2016;Bains et al,2016).…”

 Abstract: This exploration is carried out to reveal the outcome of turning factors such as cutting velocity, depth of cut and feed rate on the surface roughness, mean cutting force and tool-work interface temperature on turning cylindrical 655M13 steel alloy components. The experiments are designed based on (33) full factorial design and conducted on a turning centre with Titanium Aluminium Nitride (TiAlN) layered carbide tool of 0.8mm nose radius, simultaneously cutting forces such as feed force, thrust force and tangential force and the tool-work interface temperature are observed using calibrated devices. The surface roughness of the turned steel alloy parts is deliberated by means of a precise surface roughness apparatus. Prediction models are created for average surface roughness, mean cutting force and tool-work interface temperature by nonlinear regression examination with the aid of MINITAB numerical software. The optimum machining conditions are confirmed with the aid of a Genetic Algorithm. The outcome of each turning factor on the surface roughness, mean cutting force and tool-work interfacetemperature is studied and presented accordingly. . His current research interests include manufacturing of materials, metal cutting, metal cutting fluids and machining optimisation.
