textured tools and then subjected them to cryogenic treatment. After that, turning tests were carried out on 17–4 PH material using cryo-treated textured tools, and RSM was used to identify the ideal cutting parameters. Furthermore, it was shown that there was a good match between the anticipated and experimental findings when machinability indices were evaluated using RSM. Dinesh et al. (2016) created linear microgrooves at various angles on the tool's rake face and evaluated how well the designed tool performed during the turning of ZK60 alloy in dry and cryogenic conditions, in comparison to untextured tools. In both cutting settings, machinability with textured tools was shown to be much better than that of untextured tools. Furthermore, because of the micro pool lubricating effect over dry conditions, exceptional results were seen with both tools under cryogenic chilling conditions. Manikandan et al. (2018) examined the differences in turning performance between untextured and created textured tools for turning Ti–6Al–4V alloy under conditions of infused solid lubrication. A small layer of lubricant at the cutting zone while using textured tools under solid lubrication conditions has been shown to significantly enhance turning performance. In their 2016 study, Sharma and Pandey assessed the machining performance of AISI 4340 material using single, dual pattern textured, and untextured tools with solid lubrication. They discovered that, in comparison to untextured tools, textured tools' reduced friction was responsible for better turning performance. However, it was discovered that dual pattern textured tools performed better than single pattern textured tools. When using linear textured tools to mill VSM13 steel in dry turning, Bertolete et al. (2018) found that the textured tools performed better than the untextured ones in terms of turning performance. Different circular pit textured tool geometries were studied by Durairaj et al. (2018) for turning aluminum material. The diameter of the dimple hole was discovered to be a component that affected turning performance. Furthermore, as compared to untextured tools, textured tools perform better due to their lower stickiness. Using newly created dual textured tools, Hao et al. (2018) conducted turning tests on titanium alloy. Under MQL, dry circumstances, the results were compared with untextured and single pattern textured tools. Because there was greater coolant capacity in the two
been increasing in the present scenario due to many reforms in the environmental conscious regulation. Therefore, current study focused on sustainable machining techniques that textured tools and Minimum Quantity Lubrication (MQL) to meet the demand in the metal cutting industries. In the present work, surface textured tools were fabricated and same tools was used to assess the turning process performance during machining of EN8 material. The obtained results were compared with untextured tools under MQL cooling condition. Results indicated that while turning EN8 material, the largest decreases in cutting temperature, rake wear, flank wear, and surface roughness were reported to be 14%, 22%, 29%, and 38%, respectively, while using textured tools as opposed to untextured tools. Further, noticed that under MQL cooling conditions, the textured tools showed a micro pooling effect with microgrooves. Key Words: MQL; EN8; Textured Tool; surface roughness; tool wear
1.INTRODUCTION En8 material is frequently used in the automobile sector to manufacture shafts and axles. Therefore, it is imperative to improve this material's machinability. Using standard tools, Thangarasu et al. (2020) performed experiments on EN8 steel in a dry state. They used ANN to evaluate the turning performance characteristics and found that there was minimal inaccuracy in the correlation between the experimental and anticipated outcomes. In their 2008 study, Vamsi Krishna and Nageswara Rao examined the turning capabilities of traditional tools when machining EN8 steel in three different lubrication conditions: dry, wet, and developed solid. Compared to alternative cutting. Using Taguchi analysis, Gugulothu et al. (2020) conducted tests based on the L9 orthogonal array design to discover the ideal cutting condition for converting EN8 steel. When turning EN8 steel material, Murugappan and Arul (2017) observed a considerable drop in the chip reduction coefficient under dry ice chilling conditions as opposed to dry conditions. The tool-chip contact area has been positively impacted by surface-textured tools. As covered in the literature below, there have been a few recent attempts to transform using
