Description
Summary:Milling process is a kind of machining that allows modeling in various materials such as composites, metal, plastic, and wood etc. with complex forms and trimming pieces and in the meantime the chips elimination and processingresidues. This article investigates the machining parameter optimization for a face milling operating in a vertical CNC milling machine with a workpiece material of aluminium alloy 7075 and cemented carbide as a cutting tool. Various experiments are performed with the variation of input processing parameters such as spindle speed (Ss), feed rate (Fr), and the cutting depth (Dc). In addition, the impact of input process parameters is examined using the Taguchi design approach, which also optimizes the machining process parameters and construct the association among them w.r.t. the output response characteristic called surface roughness (SR), and material removal rate (MRR), where the optimal combination for the improved MRR is obtained at Ss of 3500 rpm, Fr of 400 mm/min and Dc of 0.3 mm and enhanced surface finish is about 3500 rpm, 400 mm/min, and 0.2 mm of Ss, Fr and Dc, respectively.
