“…Although there are several investigations into the machining of Inconel 718, it is still challenging to understand the nature and actual reasons behind the disadvantage of the machining of Inconel 718 to improve productivity and quality in manufacturing. In the most of early studies on Inconel 718, surface roughness was used as a key output and process parameters have been tuned to improve the surface quality of machined products (Zhuang et al 2015;D' Addona et al 2017;Mohsan et al 2017;Cantero et al 2018;Mehta et al 2018). Guo et al (2009) overviewed the machining characteristics of difficult-to-cut materials, including nickel-based alloys.…”

This paper investigates the influences of three different input parameters, such as feed rate, insert nose radius, and insert coating methods, in the turning operation of Inconel 718. The coating methods were selected as medium temperature chemical vapor deposition (MT-CVD) and physical vapor deposition (PVD) and in addition to coating methods, the role of various coating materials was discussed since the inserts were coated with multi-layers of TiCN/Al2O3/TiN and single-layer of TiAlN on carbide substrates. The results were discussed in terms of wear behavior of cutting tools and surface quality of the workpiece, which is indicated by surface roughness. A full factorial experimental design was employed in the present work and the results were evaluated using main effects plots. Furthermore, the analysis of variance (ANOVA) method was applied to specify both reactive and non-reactive effects of experimental parameter reactions. The results showed that surface roughness is reduced using low feed rates and large nosed inserts in the operations. Furthermore, TiAlN-coated inserts with PVD method provided better surface finish than with MT-CVD method. It was also found that surface roughness increases as the wear rate of inserts increases.

“…ze względu na dobór strategii i narzędzi skrawających [2] czy też właści-wości samego materiału obrabianego [3,6]. Stopy takie jak Inconel 718 mają tendencję do tworzenia narostów i wykruszeń na powierzchni obrobionej, które znacząco obniżają jakość SGP.…”

“…Mniejszy wydatek energetyczny podczas nagrzewania wiąże się z oszczędnością, przy jedoczesnym zadowalającym efekcie technologicznym. Warto zauważyć, że uzyskane w tej pracy parametry chropowatości Ra są niższe niż w inny pracach dotyczących laserowego wspomagania skrawania stopu Inconel 718 [6,11].…”

“…Furthermore, residual surface tensile stress was produced directly in the absence of a cutting fluid. Mohsan et al [17] showed the surface integrity of the GH4169 superalloy under different cooling conditions. The surface integrity of the GH4169 superalloy of flood cooling turning was better than that of dry turning at lower cutting speeds, but flood cooling turning had a low impact on the surface integrity of the GH4169 superalloy at higher cutting speeds due to the bubble barrier or seizure effect that hinders heat transfer between the coolant and the workpiece.…”

The GH4169 superalloy has high strength at high temperatures. Cooling conditions have a major impact on the machined surface integrity, which further affects the fatigue properties of specimens of the GH4169 superalloy. The influence of cooling conditions on the surface integrity of the GH4169 superalloy is first studied during the side milling. Then, the effect of surface integrity under different cooling conditions on the fatigue behavior of specimens of the GH4169 superalloy is investigated by a standard tensile and tensile–mode fatigue testing. The results obtained show that surface roughness and the depth of the plastic deformation layer in wet milling and dry milling makes little difference, the surface microhardness rate in dry milling is slightly lower than that in wet milling, the surface tensile residual stress in dry milling is significantly higher than that in wet milling, and the fatigue behavior in dry milling is only about 50% of that in wet milling. In addition, the crack initiation of specimens of the GH4169 superalloy utilizing wet milling is on the subsurface, while that from dry milling is on the surface. Thus, cooling conditions have an important impact on the fatigue behavior of specimens of the GH4169 superalloy, and micro defects in dry milling are the main factors of decreasing of fatigue behavior of specimens of the GH4169 superalloy.
