“…Such disarrangement could be due to abrasion that would lead to micro-cracks at WC/WC or at WC/Co interfaces or chipping due to the alternative stress. 4,10 Consequently, few deep grooves or slip line traces on the surface of WC grains on the worn flank surface were observed. In addition, a prominent adhesion layer was also found.…”

“…In general, the distinct wear mechanisms that are predominant under various cutting conditions are as follows: abrasion, adhesion, plastic deformation, oxidation, diffusion and chipping or notching. 3–5 Machining of hard materials, as in the case of WHAs, involves discontinuous chip formation, which possibly leads to formation of abrasive or adhesive wear on the flank surface with built-up edge (BUE). 6–8 Chen et al 9 evaluated abrasiveness index and observed diffusion, chemical, abrasive and micro-chipping as the major cause for rapid crater wear, while dry machining high chromium cast iron using polycrystalline cubic boron nitride (PCBN) inserts.…”

Tungsten heavy alloys are widely used in the manufacturing of weights for aircraft, missiles, boats and race cars; penetrators; radiation shielding; and radioisotope containers. Manufacturing these components needs machining as a secondary operation. Since tungsten heavy alloys are difficult to machine, the in-depth analysis of tool wear growth and mechanism during machining of these alloys becomes essential. Hence, this work focuses on the experimental study of flank wear growth and its effect on other machining outputs for two different tool geometries (−5° and 2° rake angles) during turning of 90 tungsten heavy alloys. The predominant wear mechanism was identified as adhesion based on scanning electron microscopic analysis. Finally, three commonly used analytical tool wear rate models and one newly proposed model (modified Zhao model) were utilized for the prediction of flank wear growth and tool life. It was observed that the modified Zhao model could predict tool flank wear fairly well within error percentage of 4%–7% and thus could be used as a benchmark while machining difficult-to-cut alloys.

“…BUE is an addition of material against the rake face of the cutting tool that seizes to the tool tip separating it from the chip due to the adhesion. 27,30 To observe these phenomena (oxidization and BUE formation), SEM with EDS over the cutting insert (tool surface) was examined and the same is shown in Figure 13. Figure 13(a) illustrates the EDS analyses which explained the presence of various elements (Fe, Cr, Ni, Al, Ti, Mg, and O).…”

“…Then, L 9 standard orthogonal array (OA) was designed and dry turning experiment was performed. First, second, third and fourth column were assigned to cutting speed (30,40 and 50 m/min), feed (0.01, 0.02 and 0.03 mm/rev), depth of cut (0.25, 0.50 and 0.75 mm) and error, respectively. The material removal rate of the turning operation was expressed through an equation (1) 22 :…”

Incoloy 800H is an austenitic Fe-Ni-Cr based superalloy and used in many applications due to their high corrosion resistance and creep-strength. However, this alloy is difficult to machine or cut material because of their eminent characteristics such as rapid-work hardening, lesser thermal conductivity and easy to tool-material attraction. Hence, the necessary experimental investigation is required to study and optimize the turning parameters of this alloy. This work presents the investigation of turning parameter effects on the Incoloy 800H superalloy with cryogenically treated cutting tool. The dry turning experiments were conducted based on Taguchi L9 Orthogonal array (OA) with the input parameters of cutting speed, feed rate and depth of cut. The outputs such as material removal rate, surface roughness, cutting force and tool-tip temperature were considered as the responses. The measured output responses were optimized and modeled using Taguchi-based Grey relational analysis (GRA) and response surface methodology (RSM), respectively. The tool flank wear and tool life were examined on coated insert with cryogenically treated, coated insert (without cryogenic treatment) and uncoated insert for comparison. The results revealed that greater amount of tool-wear reduction was observed in the case of coated tool with-cryogenically treated about 47.88%, coated tool without-cryogenically treated about 27.51% when compared with an uncoated tool. Besides, analysis of variance (ANOVA) was performed to find the most significant parameter over the obtained responses. The obtained mathematical model through RSM was agreed with the experimental result. Further, the machined surface topography was examined using White Light Interferometer (WLI).
