“…Sun et al fabricated micro-grooves and micro-pits on the rake face of WC/Co tools, and then studied the cutting performance of the tools. The results show that the composite texture with micro-pits and micro-slots can be used as a micro-reservoir to continuously supplement lubricating oil, thus improving the cutting performance of the mixed micro-textured cutter [16][17][18]. Wei et al conducted tribological and cutting experiments on aluminum alloy workpieces by sandblasting micro-materials and machining micro-geometric features of the rake face of the sapphire tools.…”

The insertion of micro-textures plays a role in reducing friction and increasing wear resistance of the cutters, which also has a certain impact on the stress field of the cutter during milling. Therefore, in order to study the mechanisms of friction reduction and wear resistance of micro-textured cutters in high speed cutting of titanium alloys, the dynamic characteristics of the instantaneous stress field during the machining of titanium alloys with micro-textured cutters were studied by changing the distribution density of the micro-textures on the cutter. First, the micro-texture insertion area of the ball-end milling cutter was theoretically analyzed. Then, variable density micro-textured ball-end milling cutters and non-texture cutters were used to cut titanium alloy, and the mathematical model of milling force and cutter-chip contact area was established. Then, the stress density functions of different micro-texture density cutters and non-texture cutters were established to simulate the stress fields of variable density micro-textured ball-end milling cutters and non-texture cutters. Finally, the genetic algorithm was used to optimize the variable density distribution of micro-textured cutters in which the instantaneous stress field of the cutters was taken as the optimization objective. The optimal solution for the variable density distribution of the micro-textured cutter in the cutter-chip tight contact area was obtained as follows: the texture distribution densities in the first, second, and third areas are second, and third areas are 0.0905, 0.0712, and 0.0493, respectively.

“…In this regard, Kiyota et al [16], Obikawa et al [17] reported that dimple patterns parallel to the cutting edge were effective in improving the lubrication conditions as well as reduce the cutting forces than the perpendicular textures. Orra and Choudhury [18] conducted experiments and compared micro-textured tool with un-textured tool. They reported reduction of cutting force and increase in shear angle when machining with textured tool as compared to the results of machining without micro-textures.…”

Present investigation is focused to study the impact of different lubricating environments using pure canola oil and graphene mixed in canola oil, on the performance of uncoated carbide textured tools in minimum quantity lubrication (MQL) turning of AISI 4340 hardened steel. The influence of using twin jet and single jet was also studied under MQL. The turning performance was evaluated in terms of flank wear (VB max), cutting forces, cutting temperature, and chip morphology. The results showed that MQL mist supplied simultaneously on rake and flank face of the textured tool by twin-jet nozzle performed better than MQL mist supplied on the rake face of textured tool by the single-jet nozzle. Out of all the tested lubricating environments, best tool life was achieved with nanoparticle minimum quantity lubrication (NMQL) using the twin jet followed by only oil using twin jet as compared to all other conditions tested in this study. The outcome of the study illustrates that MQL mist of graphene which is mixed in canola oil on a textured tool with the twin-jet nozzle can be successfully applied for finish turning of hardened steel.

“…The results show that, compared with traditional tools, the micro-scale deformed tool significantly reduced the cutting force, cutting temperature, friction coefficient, and tool wear, and improved the surface roughness and quality of the machined workpiece. The reduction of cutting force and cutting temperature contributes to the service life of the tool and the strength of the cutting edge, which is of great significance in precision hard turning [14].…”

The hard turning process has been widely used in the field of hard material precision machining because of its high efficiency, low processing residual stress, and low environmental pollution. Due to its undesirably processing quality, it is still not a substitute for traditional grinding, so many studies have reported that the process has been optimized. However, there has been little research on the geometry optimization of hard cutting tools, which have a great influence on the traditional machining process. In this paper, two tools with different rake face shapes are designed. The finite element analysis method is used to compare their performance with a conventional plane tool while turning hardened steel. The results show that the cutting performance of the designed tool T1 and T2 (chip morphology, cutting force, and cutting temperature) and the quality of the machined surface are improved compared with the tool. The cutting force decreased by 12.72% and 14.74%, the cutting temperature decreased by 7.56% and 9.01%, respectively, and the surface residual stress decreased by 26.56% and 28.66%.
