Multi-Response Optimization of Milling Process Parameters for Aluminium-Titanium Diboride Metal Matrix Composite Machining Using Taguchi- Data Envelopment Analysis Ranking Approach

The demand for hybrid composite materials has been expanding globally in all kinds of mechanical industries. Drilling is one of the basic operations required in manufacturing of various components and choosing optimum parameters of drilling is vital for getting good quality holes. The main objective of our work is to determine the ideal parameters of drilling and tool coatings required to minimize the thrust force and torque in drilling and to maximize the material removal rate (MRR) using Grey–Taguchi technique. Hybrid composite specimen made by reinforcing Al7075 alloy with 4% of aluminum oxide and 2% of boron nitride in stir casting process and drilling was carried out in a sequence at different drilling feed rates (40, 80, and 120 mm/min) and spindle speeds (1,200, 2,400, and 3,600 rpm) in a vertical machining center attached with drill tool dynamometer, using twist drills of diameter 5 mm and point angle 118° made of uncoated carbide, diamond-like carbon (DLC)-coated carbide and high carbon (HC)-coated carbide. The recorded thrust force and torque from the dynamometer and the computed MRRs during each drilling operation are tabulated as per Taguchi’s L27 orthogonal array and the results are analyzed using hybrid Grey–Taguchi technique. In our analysis, the optimum thrust force of 62.12 N and torque of 0.766 Nm were obtained when using a DLC-coated tool at a maximum speed of 3,600 rpm and minimum feed rate of 40 mm/min. An optimum MRR of 178.79 mm3/s was obtained while using DLC coated at a maximum speed of 3,600 rpm and a maximum feed rate of 120 mm/min.

“…The presentation intends to assist in making multi-criterial decisions for production and research engineer. The graph reveals that an increase in cutting speed and depth of cut increased the Pt, i.e., they contribute positively to the multi-performance response of the manufactured PA6 62 , 63 . But it is shown that an increase in feed rate decreased the Pt of the manufactured PA6 64 , 65 .…”

Polycaprolactam (PA6) is a thermoplastic polymeric material and because of its excellent mechanical properties, it has found an extensive application in military, textile, biomedical, building and construction, and several others. Because of its extensive applications, machine turning operation becomes a crucial section in the manufacturing of high-grade PA6. Hence, to have a high-grade PA6, turning operational conditions (cutting speed, feed rate and depth of cut) are optimized on the three surface profile responses and one material removal rate (MMR) with help probability based multi-response optimization analysis. This analysis is employed for an efficient multi-criterial decision making when PA6 is manufactured with a turning operation machine. The result revealed an optimal turning operational conditions to be 860 rpm cutting speed, 0.083 mm/rev feed rate, and 4 mm depth of cut. Furthermore, the analysis of variance and the numerical presentation of the turning operational conditions revealed that the feed rate is the most significant condition with a contribution of 34.09%, followed by cutting speed with a contribution of 32.05%, and then depth of cut with a contribution of 28.62%. Also, the confirmation analysis revealed a very high efficacy of the multi-objective optimization method employed in this study. This suggests that probability based multi-objective optimization is efficacious for optimizing machine conditions of any manufactured engineering material. It is interesting to state that the high confidence level placed on the considered turning operational conditions gives room for probable machine conditions adjustments for better PA6 in the case where different machine types are employed.

“…Some existing synthetic applications fall into this category. A reliable antiwetting behavior of surfaces over extended periods is essential for many industrial applications of nonwetting surfaces. − Wear, erosion, corrosion, and oxidation are some of the degradation processes that surfaces experience in industrial applications. − In addition, UV degradation is another challenge for SHCs. During the day, sunlight produces a large dose of UV light, generating free radicals on polymeric surfaces .…”

Aluminum is vulnerable to corrosion, biofouling, and durability reduction as a result of forming unwanted deposits during their interactions with liquids. In this work, a high-corrosion-resistance superhydrophobic coating (SHC) of poly(vinylidene fluoride-co-hexafluoropropylene)/carbon nanotubes was fabricated employing an electrospinning technique and spray coating. The dispersed carbon nanotubes were sprayed into the electrospun poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) to avoid galvanic corrosion. The as-prepared SHC exhibited a water contact angle (WCA) of 156 ± 2°and a tilting angle of 3 ± 2°. The wettability and the corrosion resistance of the PVDF-HFP/CNTS SHC were evaluated before and after exposure to UV in 3.5 wt % NaCl. The surface morphology and topography were explored before and after exposure to UV using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Employing the electrochemical impedance spectroscopy (EIS) revealed that the as-prepared PVDF-HFP/CNTsSHC has a high corrosion resistance over the immersion in 3.5 wt % NaCl for 1 month.
