Investigation on Some Machinability Aspects of Inconel 825 During Dry Turning

Integrated optimization methodology for intelligent machining of inconel 825 and its shop-floor application

“…From the review of literature, three parameters that influence surface roughness in turning process, viz., spindle speed (N)/cutting speed (v), feed rate (f), and depth of cut (d) are considered as process parameters. A number of researchers have used these parameters in their investigation during turning of Inconel alloys [31,32]. The typical values of these parameters are 25/35/45 m/min, 0.1/0.15/0.2 mm, and 1.0/1.25/1.5 mm for v, f, and d, respectively.…”

“…They conducted turning experiments on hardened AISI 4140 steel based on L 9 orthogonal array. Thakur et al [11] investigated the surface morphology, chip characteristics, and tool wear during dry turning of Inconel 825 using coated and uncoated CVD tool. They found that the minimum surface roughness and tool wear obtained in the higher cutting speed using uncoated carbide tool.…”

On Applicability of Multilayer Coated Tool in Dry Machining of Aerospace Grade Stainless Steel

“…3a) Excellent resistance of coated tool (Fig. 5) for nose wear can be explained to higher chemical inertness and thermal stability including hot hardness of Al 2 O 3 coating of CVD multilayer coated carbide insert [18][19][20][21][22][23]. Fig.…”

“…The anti-friction property, hardness, chemical inertness and thermal stability of coated tools often makes them best choice for machining such category of hard-to-cut materials. Various coatings such as TiN, TiC, TiAlN, TiCN and Al 2 O 3 have been deposited over cutting tools with different techniques to improve the machinability aspects of other hard-to-cut materials such as hardened steels and nickel-based super alloys [4][5][6].…”

On the Machinability and Surface Finish of Superalloy GH909 Under Dry Cutting Conditions

“…While turning N-155 iron-nickelbase superalloy, Davoodi and Eskandari 20 found that cutting speed was the most significant factor and the most dominant tool failure modes were adhesion wear. During dry machining of Inconel 825, Thakur et al 21 et al found the dominating tool wear mechanism were abrasion, adhesion, and diffusion wears. Zhu et al 22 concluded that the actual wear rate is the combination of adhesion, abrasion, diffusion, and oxidation wear rate in cutting of Nickel-based alloy, depending on the temperature and stress distributions.…”
