Optimization of Micro Drilling Parameters of B4C DRMM Al 6063 Composite in μECM Using Taguchi Coupled Fuzzy Logic

Abstract

Increased demand of advanced material like B 4 C DRMM Al composite due to its excellent mechanical, thermal properties puts the pressure on manufacturing sector because of its machining complication. In this research study, the B 4 C reinforced Al composite with 15% volume fraction has been developed with stir casting route. Micro holes ranging from diameter 0.38mm have been made over the composite specimen of thickness 0.4 & 0.5mm for which Micro Electro chemical Machine was employed. Totally nine experiments were conducted based on L9 orthogonal array emphasized by Taguchi's technique and the optimum levels were predicted based on the average S/N graph method. During the experiments frequency, voltage, current and electrolytic concentration were considered as the process variables, thereby considering the machining time as the response variable. Additionally, the analysis of variance (ANOVA) has been applied to determine the most significant factor to influence the response. In order to enhance the degree of validation, unconventional optimization tool of fuzzy logic was also employed to compare the results of the optimized model. Results of fuzzy logic and Taguchi's method were deviate in zero tolerance.Click here and insert your abstract text.

Optimization of Surface Roughness Parameters of Al-6351 Alloy in EDC Process: A Taguchi Coupled Fuzzy Logic Approach

“…It is based on intuition and judgment and it does not need a mathematical model to construct [12]. Fuzzy logic system (Mamdani system) comprises of a fuzzifier, membership functions, a fuzzy rule base, an inference engine, and defuzzifier.…”

A comprehensive analysis to assess the impact of nano MoS2 on the wear characteristic of Al-TiB2-Gr composite

“…But the oxidation of the melt results in poor wettability with the reinforcing particles. An inert atmosphere was created to increase the wettability by adding a small amount of Mg with the melt [27]. The premeasured and preheated graphite, TiB 2 , and nano MoS 2 reinforcing particles were mixed into the melt.…”

“…It is an important technique to address the minimum number of combinations of experiments by considering the number of dependent and independent variables at their levels [27,29]. The L9 orthogonal array was recommended for the existing work with the three-parameter and two objectives.…”

Leverage of Environmental Pollutant Crump Rubber on the Dry Sliding Wear Response of Epoxy Composites

“…It is essential to address the combination of experiments by considering the number of dependent and independent variables at their levels. The number of experiments can be minimized with the implementation of this technique [23,24]. The L9 orthogonal array was followed for the present work with three parameters and two objectives.…”
