“…During the trials, depth of cut was constant (0.6 mm) and cutting speed, feed rate, and approach angle, and are varied to four levels and to examine the consequence on the three components of the cutting forces and the on the tool-edge temperature variations. The PVD based inserts generate improved results contrasted to coated inserts (CVD) regarding machining forces components and tool-cutting edge temperature [76].…”

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.

“…They found the use of MQL with Nano-graphite fluid considerably reduced surface unevenness, cutting force, machining temperature and tool wear by 30%, 54%, 25% and 71%, respectively, compared with wet machining. Also, the comprehensive literature review has been done by Sharmaet al [18] in which, the effect of MQL technique is compared with other machining operations for different Nano fluids and conventional cutting fluids.…”

The use of cutting fluid by industrial manufacturers has benefited the machining processes, effectively. Cutting fluids reduce the temperature of the surface, frictional effects; it also removes chips by flushing them and therefore extends tool lifespan by improving machining performance. However, the consumption of excess amount of cutting liquid arises concern in regard to production rate and ecological problem. Therefore, a common target of manufactures is to develop a safer working atmosphere and reduce production cost by drastically reducing the use of cutting fluid in machining. The feasible solution to achieve this goal is minimum quantity lubrication (MQL), in which we deliver the lubricant at very small flow rate to machining zone. MQL technique has evidence, as it is suitable to comply for the fulfillment of 'Green Machining'. Therefore, in this study, the effects of MQL in turning, drilling, grinding and milling application using mineral oils (base oils), vegetable oils (synthetic oils), and Nano-fluids on various materials are discussed.

“…Studies point to the effectiveness of the application of MQL in steel turning. In [18], the machining performance of AISI 4340 steel under MQL turning is better than dry turning because both the machining force components and cutting tool temperature decrease, which consequently favors chip-tool interaction and maintains the cutting edges sharp. In [19], the application of MQL overcomes the lubri-cooling strategies on dry, compressed air cooling and flood cutting fluid due to the lower surface roughness and reduced tool-wear rate generated by AISI 4340 turning.…”

The literature review shows few studies concerning the turning of hardened steels using carbide tools. A research in this case can provide a better understanding and an option of inserts with less cost than usually applied ceramic and CBN (cubic boron nitride) inserts. Thus, the objective is to investigate the tool-life of ISO P and ISO S grade coated carbide inserts and average roughness (R a) of the machined surface generated with these tools in the hard turning of AISI 4140 steel under dry and minimum-quantity of lubrication (MQL) conditions. Comparing the ISO P and ISO S grades tool life in two different cutting speed levels (60 and 120 m/min), the higher cutting speed generated the lowest R a values. Relating the lubri-cooling conditions, dry turning resulted in lower R a values. When the tool nose wear does not change during the passes, the R a remains constant. In addition, ISO S grade coated carbide insert has shown a possibility for this hard turning due to the low tool nose wear at a relatively high cutting speed.
