“…Surface texturing is explained in two parts: (i) various sources for the creation of surface textures and (ii) types of textures reported. Metal forming, micro/nano machining, electrochemical machining, mechanical micromachining and thermal energy micromachining are the various sources for creating surface textures as discussed in the literature 10 . From the list of available sources, electro discharge machining (EDM) and laser surface texturing under thermal energy micromachining are the commonly used techniques due to their easy availability, accuracy and lesser time for creating the textures.…”
The newer methodology to improve the performance of cutting tool is by the constructive method of micro-texturing and green synthesized nanoparticles into the texture gaps for self-lubrication. Cross-chevron textures were made on the rake face of the cemented carbide tool using Neodymium Doped Yttrium Aluminium Garne (Nd-YAG) laser texturing machine. The environmentally friendly, non-hazardous and rapid method of producing nanoparticles was followed to produce Al2O3 nanoparticles. Various techniques used for characterizing the synthesized Al2O3 nanoparticles are Potential of Hydrogen (pH), Fourier Transform Infra-Red Spectroscopy Analysis (FTIR), Dynamic light scattering (DLS) and X-Ray Diffraction (XRD). The XRD shows the presence of required functional groups and the size of nanoparticles in the range of 500–550 nm. This article discusses the effect of textures, with and without nanoparticles filled on the texture gaps of the cemented carbide tool on the main cutting force, thrust force and co-efficient of friction while machining austenitic stainless steel 304. The combined effect of surface texturing and lubrication of Al2O3 nanoparticles enhanced the performance of the cutting tool compared with the conventional and textured tool.

“…The textures are formed either on the flank or rake surface. Enhancement of the basic tribological properties leads to enhancement in lubrication capability, which assists in minimizing the cutting tool wear, augment surface roughness, and the components of metal removing forces [39]. An efficient technique to improve machining behavior is to eradicate the heat from the deformation areas.…”

“…The manufacturing efficiency of any machining practice generally depends on metal removal forces as this response is reliant directly on the insert material, geometrical parameters, work material like hardness and depthness of cut, cutting pace, feed rate) [39]. Impingement of cutting fluid presents competent heat transfer leading to lesser cutting temperatures compared to traditional wet turning [27].…”
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.
“…Feng et al [21] indicated that the cutting force and cutting temperature could be significantly reduced when a textured tool was used. As a conclusion, the textures on the tool surface can effectively reduce the tool-chip contact surface, reduce cutting temperature and cutting force, store lubricant, improve the contact state, and decrease the adhesion phenomenon [22][23][24][25]. However, the effect of sinusoidal textures and rhombic micro textures of tools on the cutting performance of titanium alloy is still unclear, which is necessary to be studied to further improve the cutting efficiency and surface quality of titanium alloy.…”
Titanium alloys are widely used in various fields, but their machinability is poor because the chip would easily adhere to the tool surface during cutting, causing poor surface quality and tool wear. To improve the cutting performance of titanium alloy Ti-6Al-4V, experiments were conducted to investigate the effect of micro textured tool on the cutting performances. The cemented carbide tools whose rake faces were machined with line, rhombic, and sinusoidal groove textures with 10% area occupancy rates were adopted as the cutting tools. The effects of cutting depth and cutting speed on feed force and main cutting force were discussed based on experimental results. The results show that the cutting force produced by textured tools is less than that produced by non-textured tools. Under different cutting parameters, the best cutting performance can be obtained by using sinusoidal textured tools among the four types of tools. The wear of micro textured tools is significantly lower than that of non-textured tools, due to a continuous lubrication film between the chip and the rake face of the tool that can be produced because the micro texture can store and replenish lubricant. The surface roughness obtained using the textured tool is better than that using the non-textured tool. The surface roughness Ra can be reduced by 35.89% when using sinusoidal textured tools. This study is helpful for further improving the cutting performance of cemented carbide tools on titanium alloy and prolonging tool life.
