<p>Engineering materials have evolved tremendously in today’s environment. Because conventional materials are failing to meet the needs of todays applications, a variety of composites are being developed to solve these difficulties. In the majority of cases, the most important manufacturing procedure is turning, and the cutting tool’s state and its input parameters have the biggest impact on surface finish. For a long time, academics and professional engineers have been interested in the process of finding optimal settings for turning innovative composite materials. Al7075/ZrO2 composites are created in this study by stirring casting with 4 wt % zirconium dioxide (ZrO2) as reinforcement and Al7075 aluminum alloy as matrix. The L9 orthogonal array was used to identify the best machining settings by altering the input parameters on the fabricated composites. The goal of the present investigation is to use Taguchi analysis to determine the ideal cutting parameters for the innovative composite Al7075/ZrO₂ while focusing on surface roughness.</p>
