Summary: This study aims to investigate the influence of brushing the cutting edge on cutting force, energy consumption, tool wear, and cutting edge temperature during the production of turbine disc dovetails. The results show that increasing the cutting edge radius significantly affects the cutting force and surface quality. Through experimental tests and simulations, it was found that a 12 μm cutting edge radius exhibits the best performance.

Summary: This study investigates the cutting process of nickel-based superalloy Inconel 718 with worn tools using both numerical and experimental methods. The results show that worn tools have an influence on thermal distribution, force variation, and tool wear performance. A white layer appears on the subsurface due to intense friction and significant heat generation caused by tool wear, altering the stress condition and thermal distribution. EBSD and SEM results demonstrate variations in subsurface material and deformation under different cutting conditions. The findings from both numerical and experimental methods are consistent, highlighting the ability to study cutting performance with worn tools numerically and reducing resource requirements for studying surface deformation.

Summary: A new machining method, cryogenic-ultrasonic vibration-assisted milling (CUVAM), was proposed to improve the workability of Inconel 718. The study compared the effects of conventional machining (CM), cryogenic cooling machining (CCM), and CUVAM on cutting force, chip, tool life, workpiece surface morphology, and surface integrity. The results showed that cryogenic assistance could improve the machining environment and coefficient of friction, while ultrasonic vibration assistance in CUVAM suppressed the increase in cutting force. Compared to CM, CUVAM reduced cutting force by 36.5% and had a beneficial impact on tool life. The surface roughness after CUVAM was also significantly reduced compared to CCM.

Summary: In this paper, the performance of three microtextured tools in machining Inconel 718 high-temperature alloy under different coating conditions was investigated using the finite element method. Theoretical models were established to analyze the cutting force and cutting temperature of the microtextured tool. The effect of changing the coating material on the machining performance was discussed, and it was found that adding coating materials to the tool surface can effectively improve machining efficiency.

Summary: This article investigates the machining of DMLS Inconel 718 alloy parts using longitudinal turning with CBN tool inserts. The authors propose an optimization algorithm to find the optimal finishing cutting parameters while minimizing cutting force and considering surface quality. Experimental results show that the additive method of machining results in lower cutting force and specific cutting force compared to the cast material. The study also reveals that changing the cross-sectional shape of the cutting layer can further reduce the specific cutting force.

Summary: The research found that using sunflower oil based MQL environment can significantly reduce the size effect region and tool wear, decrease edge radius, tool flank wear, and cutting forces. In addition, an increase in microhardness, relatively smooth surfaces, and reduced micro cracks, prows, and voids on the machined surfaces were observed when applying MQL.

Summary: Inconel 718 micromilling can produce spheroidal chips due to high-speed oxidation and exothermic reactions. The process may also lead to the formation of helicoidal and ribbon chips, with ribbon chips attributed to increased cutting in the minor cutting edge. Further research is needed to optimize this machining process.

Summary: Inconel 718, a nickel-based superalloy, is well-known for its excellent physical and mechanical properties at high temperatures. However, its high strength and hardness lead to poor machinability. Many studies have been conducted to understand and optimize the machining of Inconel 718, with a focus on cutting parameters and machinability features such as cutting tool wear, cutting forces, and surface reliability.

Summary: The demand for Inconel-718 miniature parts has grown due to the development tendency of miniaturization. However, the non-negligible edge radius and property anisotropy result in volatile machinability and inferior quality, hindering the wide application of Inconel-718 miniature parts. This research aims to clarify the material removal mode and machinability of Inconel-718 micro-cutting by considering strain-rate sensitivity and strain-rate inhomogeneity, and the results show the influence of various cutting conditions on material removal mode and machinability.
