“…Thus, the best results in terms of tool life time were those obtained for both low cutting speeds and feeds. The tool life obtained for the cutting speed of 50 m/min and 0.1 mm/rev feed was very close to those obtained by the authors in analogous tests, where a conventional pressure coolant was used [11]. However, a great influence of the cutting speed in the tool life has been found, decreasing its life up to 85% when the cutting speed increases from 50 to 70 for a feed of 0.1 mm/rev, and up to 90% for a feed of 0.15 mm/rev.…”

“…Nevertheless, in the bibliography, there are general recommendations establishing the ranges for the cutting speed (30-35 m/min), feed rate (0.1-0.18 mm/rev), and depth (1 mm) [31]. Moreover, Díaz-Álvarez et al [11] investigated the machining of Haynes 282 with carbide tools under a conventional pressure coolant using cutting speeds between 50-90 m/min, feeds between 0.1-0.15 mm/rev, and a depth of pass of 0.25 mm, obtaining a maximum tool life of 33 min. Thus, the cutting parameters selected for the present study are summarized in Table 2.…”

“…In Table 3, both the tool life values by means of cutting time, the machined surface per time (S mach.t ) and the machined surface per cutting edge (S edge ), quantified through Equations (1) and (2), respectively, have been summarized for all of the cases analyzed [11].…”

“…A negligible effect for the high-pressure cooling was observed, while the solution annealing large grain solution (LGS) state presented enhanced machinability when compared to the precipitation hardened large grain aged (LGA) state in terms of force levels and tool wear. Díaz-Álvarez et al [11] studied the performance of a coated carbide tool during the finishing turning of Haynes 282 with a cutting fluid at the conventional pressure, observing that, for all of the cutting conditions, the tool broke because of the fragile fracture of the cutting edge.…”

Nickel-based superalloys exhibit an exceptional combination of corrosion resistance, enhanced mechanical properties at high temperatures, and thermal stability. The mechanical behavior of nickel-based superalloys depends on the grain size and the precipitation state after aging. Haynes 282 was developed in order to improve the creep behavior, formability, and strain-age cracking of the other commonly used nickel-based superalloys. Nevertheless, taking into account the interest of the industry in the machinability of Haynes 282 because of its great mechanical properties, which is not found in other superalloys like Inconel 718 or Waspaloy, more research on this alloy is necessary. Cutting tools suffer extreme thermomechanical loading because of the high pressure and temperature localized in the cutting zone. The consequence is material adhesion during machining and strong abrasion due to the hard carbides included in the material. The main recommendations for finishing turning in Haynes 282 include the use of carbide tools, low cutting speeds, low depth of pass, and the use of cutting fluids. However, because of the growing interest in sustainable processes and cost reduction, dry machining is considered to be one of the best techniques for material removal. During the machining of Haynes 282, at both the finishing and roughing turning, cemented carbide inserts are most commonly used and are recommended all over the industry. This paper deals with the machining of Haynes 282 by means of coated carbide tools cutting fluids (dry condition). Different cutting speeds and feeds were tested to quantify the cutting forces, quality of surface, wear progression, and end of tool life. Tool life values similar to those obtained with a lubricant under similar conditions in other studies have been obtained for the most favorable conditions in dry environments.

“…While machining nickel alloys with any carbide cutting tools, the tool failure is due to flank wear, notch wear and built up edge formation [17]. During metal cutting, the shear force generated at the cutting edge affects flank face more than rake face.…”

In this research, an investigation on machinability of nickel-based superalloy (Inconel 600) under the influence of textured tungsten carbide cutting tools is conducted. Two main machinability indicators, namely, wear and life, have been investigated. Three types of micro-texture patterns i.e. dimples, lines and splines are laser engraved on the flank face of the cutting tool. Experiments are done with different cutting velocities, feed rate and depth of cut considering the texture pattern one among the input parameters. Firstly, while machining Inconel 600 with plain (non-textured) tungsten carbide cutting tool, it is investigated that at low velocity, the cutting nose caused damage due to abrasion and friction between the tool-chip interface. Severity in tool edge has increased along with adhesive wear and builtup edge at the cutting radius with increase in velocity. Thereafter, using textured on the tools, it is observed that the cutting tool wear resistance has tremendously increased with different textured patterns due to significant reduction in friction and heat. At low velocity (50 m min −1 ) the tool wear measured is in the range of 100-150 μm and maximum of 394 μm at high cutting velocity of 150 m min −1 . The tool life was calculated using Taylor's equation based on Gaussian method. Tool lives for dimple and line textures are found superior. It is concluded that textured tools have potential to machine hard materials like Inconel superalloys with longer tool life.

Machining processes on heat-resistant superalloys—i.e., turbine cases, rings, or shafts—are challenging tasks. The high-added value of such parts makes cycle times be longer than expected. Recently, high-feed turning technique has attracted the attention of practitioners due to its high material removal rate capability. PrimeTurning™ tool unifies the concepts of high-feed and multidirectional turning using multiple active cutting edges. It should be capable of reducing machine downtimes in that kind of parts. However, to avoid early tool replacement and rejects on high added value parts, a deeper knowledge on the high-feed turning process is necessary. Here, inserts specifically designed for high-feed turning in heat resistant Inconel 718© alloy were tested using three cutting-edge angles. The results showed that when chip thickness is more relevant, a cutting-edge angle of 30° reduces the likelihood of notches. Even if force components are high, surface roughness is improved and the risk of fractures is minimized, together with a high evacuation volume. On the other hand, increasing the cutting-edge angle (45° and 60°) without compensating the feed rate, tends to produce tool fractures due to chip overload. Besides, experimental tests showed that long tool-to-workpiece contact times, tend to shorten tool life, due to excessive heat accumulation and poor chip control.
