“…The dry hard machining appeared due to its improved performances although it is challenging to turning the hardened materials with commonly coated insert without the use of coolants [4,82]. For large scale manufacturing industries with a high production rate, the dry condition machining is desirable [10].…”

“…In hard turning, nanocrystalline and nanocomposite coating improves the performance of machining and tool life, and also improve the better-machined surface integrity [78] Coated carbide tool (Al2O3) have better abrasive wear resistance (approximate 4.6 times) than uncoated one [79]. The PVD coated multilayered carbide inserts perform better on hardened AISI 4340 steel under different environments without any tooling failure or catastrophic failure [10]. The discontinuous chip is because of the internal crack formation and propagation in the cutting tool front [80].…”

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.

“…Consequently, they reported that MQL application decreased Ra and cutting tool wear compared to dry cutting and Ra increased when the feed rate increased. 19 In the end of a similar study carried out by utilizing AISI 420B martensitic stainless steel by Bruni et al., they declared MQL did not provide any advantages when compared with dry cutting in the context of the cutting tool wear and Ra. 20 In the study performed by Khan and Dhar, they compared dry cutting and MQL application in turning of AISI 1060 in the context of Fc, Ra, and tool wear.…”

In this work, it is aimed to study the effects of dry machining and minimum quantity lubrication application on machinability in turning AISI 4140 steel by utilizing different cutting parameters. Also, this study contains effects and optimization of cutting conditions (dry and minimum quantity lubricating), feed rate, and cutting speed on surface roughness (Ra) and main cutting forces (Fc) determined by employing the Taguchi method. At the end of experiments, it was established that compared to dry machining operations, minimum quantity lubricating significantly reduced cutting tool wear, while Fc and Ra decreased in general. Analyses of variance, regression analysis, signal-to-noise ratio, and orthogonal array were employed to analyze the effects and contributions of independent variables on dependent variables. The optimum levels of the dependent variables for reducing Fc and Ra using signal-to-noise rates were established. According to signal-to-noise ratios, minimum quantity lubricating had a more important effect on Fc and Ra than dry machining. The optimal conditions for Fc and Ra were at 0.16 mm/rev feed rate, 125 m/min cutting speed at minimum quantity lubricating. Analysis of variance results demonstrated that the feed rate is the most influential independent variable on Fc (93.976 %) and Ra (89.352 %). Validation test results exhibited that the Taguchi method and regression analysis were highly achieved methods in the optimization of independent variables for dependent variables. Taguchi optimization technique and regression analysis obtained from Fc ([Formula: see text] = 0.972 and [Formula: see text] = 0.997) and Ra ([Formula: see text] = 0.985 and [Formula: see text] = 0.996) measurements match really well with the experimental data.

“…The results show that the color of chips can reflect the cutting temperature and cutting speed when AISI 4340 steel is cut at high speed. The appearance of bright blue color chips indicates that the cutting speed is greater than 150 m/minute [6,7]. The chips are bright blue because the high cutting speeds result in high cutting temperatures, while the high cutting temperature is due to the high frictional forces between the flowing chips and the rake face [8,9].…”

The cutting performance of cutting tools in high-speed machining (HSM) is an important factor restricting the machined surface integrity of the workpiece. The HSM of AISI 4340 is carried out by using coated tools with TiN/TiCN/TiAlN multi-coating, TiAlN + TiN coating, TiCN + NbC coating, and AlTiN coating, respectively. The cutting performance evaluation of the coated tools is revealed by the chip morphology, cutting force, cutting temperature, and tool wear. The results show that the serration and shear slip of the chips become more clear with the cutting speed. The lower cutting force and cutting temperature are achieved by the TiN/TiCN/TiAlN multi-coated tool. The flank wear was the dominant wear form in the milling process of AISI 4340. The dominant wear mechanisms of the coated tools include the crater wear, coating chipping, adhesion, abrasion, and diffusion. In general, a TiN/TiCN/TiAlN multi-coated tool is the most suitable tool for high-speed milling of AISI 4340, due to the lower cutting force, the lower cutting temperature, and the high resistance of the element diffusion.
