“…In this context, a saw tooth is generated due to the development of built-up edge. 72 The commencement of the saw-tooth chip instigation is because of an adiabatic shear on the cutting tool edge with a propagating pathway in the direction of the free surface. 73 As reported by Vyas and Shaw 74 saw-tooth features with brutal serrations of the formed chip validate the characteristic of hard part turning because of the periodic rise of cracks in the work surface due to plastic deformation.…”

AISI 4340 hardened steel is usually used in axle shafts, main shafts, gear, and couplings. Using multi-layer physical vapor deposition a coated tool, an attempt was made to optimize the input variables on precise turning on hardened AISI 4340 grade steel. The cutting speed, feed rate, and depth of the cut were the applied process factors in the dry-cutting environment. Furthermore, surface roughness (Ra), flank wear (VBc), cutting temperature ( T), and chip morphology were considered as technological responses. The Taguchi L27 standard orthogonal array with three levels and three factors was used in the experiment. Furthermore, scanning electron microscopy and energy dispersion spectroscopy were used to analyze tool wear and chip morphology characteristics. The relevance of the input process factors on the measured responses was determined using analysis of variance analysis. The feed rate was observed to have a dominant impact on the surface roughness in the trials. At an optimal parametric combination with 80 m/min cutting speed, 0.05 mm/rev feed rate, and 0.3 mm depth of cut obtained from the Taguchi-TOPSIS optimization method. The enhancement of the closeness coefficient was observed to be 0.2372. The generated second-order regression model was demonstrated to be of high significance. The strategy and outcomes of this research will help metal machining enterprises to augment manufacturing productivity when working with hardened steel.

“…The degree of hardness and speed of abrasive grains is extremely high. It is possible to achieve surfaces with high machining precision [38]. Because of the benefits of grinding, the temperature in this particular machining process can reach quite high temperatures, deepening the plastic deformation, which causes the remaining chips from the milling process to be small.…”

Tribology has been significantly contributing to materials, energy conservation and engineering innovation. This paper elaborates the development of tribology considering in detail in energy factor, tribological role of efficiency in the society by introducing lubricants which reduces the effective friction while moving the mass which significantly improves overall efficiency of the process all though it was primitive. The objectives of the study of The American Society of Mechanical Engineers (ASME) are working to expand energy conservation, particularly through tribology, by doing things like evaluating the realistic effects of tribological innovation on conserving energy and trying to promote advanced energy technologies, identifying fields the application's location of new or existing Knowledge of tribology is anticipated to result in significant direct or indirect benefits, and so on. The strategy focuses on fluid film and rolling element bearings, consistently sophisticated metal processing, wear and friction reduction, variable power transmission, sealing technologies, automobile engines, and energy technologies. Additionally, the potential savings for various areas are detailed, as is a summary demonstrating the advantages that may be obtained with cutting-edge industrial machinery and processes, and comparing the prospective cost savings with the benefits ratio of the many key program features. road transportation for increasing energy efficiency. It was regarded as the most appropriate and advantageous aspects of tribology at the time to increasing productivity. Since then, numerous studies have focused on the study of industry-based machine and method-specific materials. Also, continuous variable transmissions are now found in many automobiles to enhance vehicle efficiency. Some future challenges were also looked at to plan and see how they can be tackled. The implementation of next level materials in different aspects of technology can lead to growth in the efficiency, quality of engineering parts and machines. This paper is a summary of the improvement in high performance materials both inorganic and organic based. It involves thin hard coverings of their growing importance in tribological improvements for tribo- engineering implementations are looked at and studied. Results from research concerning ceramics and ceramic properties, polymers and polymer properties as well as hard coatings and show the friction and wear attributes and their potential implementation for tribo- engineering. Greasing and friction have a strong relationship with wear. The study of these three topics is essentially what tribology entails. It deals with moving, interacting surfaces in science and technology. To better regulate friction and wear, hard or soft film coating, alloying, and composite structures have all been enhanced. It is accomplished by enhancing the lubricity and wear life of materials and surfaces using novel, modified lubricants and ideas that have been put to the test in challenging tribological applications. The development of new generations of self-lubricating coats with multilayered architecture due to recent advances in thin film deposition methods treatments. The field of tribology is crucial to lowering the levels of emissions from various industries because it is being used to cut down on the amount of unnecessary energy used by mechanisms. Understanding the functions of friction and wear between two surfaces that come into contact has been the domain of tribology for many decades. They have applied this knowledge to make mechanisms more energy efficient by only using what is necessary to power them and reducing the amount of energy lost through wear and friction.

The present investigation aimed at a sustainable green turning operation of Ti-6Al-4V alloy using multi-objective optimization of surface roughness, tool flank wear, material removal rate, and tool wear loss with cutting speed, feed rate, and depth of cut as input parameters. The experiments were performed on a CNC lathe machine using an alumina-zirconia (Al 2 O 3 -ZrO 2 ) ceramic insert under a dry machining environment. The experiments were performed to examine the influence of input parameters with three levels and their interactions on the output responses. The experiment trials were designed according to Taguchi's L 25 orthogonal array. A hybrid approach of grey Taguchi-based response surface methodology (GT-RSM) was exposed for estimating the optimal integration of turning parameters. The weights to the output characteristics were assigned by the analytical hierarchy process (AHP). According to the ANOVA, cutting speed was the most influencing factor in the grey relation grade (GRG) succeeded by the depth of cut and feed rate. The optimized turning settings improved the surface roughness, tool flank wear, and tool wear loss by 10.31%, 6.51%, and 7.69% respectively with a 2.21% decrease in material removal rate. The result indicated that the GT-RSM methodology provided an excellent database that was effective to enhance the output quality responses. Keywords: dry machining, alumina-zirconia (Al 2 O 3 -ZrO 2 ) ceramic insert, hybrid methodology, analytical hierarchy process (AHP), ANOVA.
