Optimization of drilling process parameters of AA7150/MoO3 composites using Taguchi method

Abstract

Aluminum 7150 has established a wide variety of uses in aerospace, industrial, architectural manufacturers, frames, tubes and pipes due to its unique properties and the Mechanical properties of aluminum alloy 7150 composites (AMCs) reinforced with 40-µm molybdenum-trioxide particles were examined in this work. This experimental work was highly focused on optimized the surface roughness analysis of AA7150 – Molybdenum Trioxide (MoO3) AMCs with three machining variables. The superior strength AA7150 alloy is perceived for this function and boosts the strength by strengthening MoO3 particles with various mass proportions. The AA7150/MoO3 AMCs are manufactured via the melt stir casting method. The optimization of the drilling variables for this analysis was regarded as drilling feed (40, 80, 120 mm/min), machining speed (800 rpm, 1200 rpm and 1600 rpm), and weight proportion of MoO3 particles (4 percent, 8 percent and 12 percent). In this process, spindle speed, feed and filler materials were used as input process variables for the drilling operation. Surface roughness was taken as the response parameters.
