Abstract: Computer Numerical Control (CNC) milling is a precision machining process used to manufacture complex and accurate components by controlling machine tools through programmed instructions. It plays a vital role in modern manufacturing industries due to its repeatability, flexibility, and high dimensional accuracy. CNC milling performance mainly depends on process parameters such as spindle speed, feed rate, depth of cut, and tool geometry. From an expert manufacturing perspective, CNC milling combined with Computer-Aided Manufacturing (CAM) enhances productivity by optimizing tool paths and machining parameters before actual production. The use of CAM software reduces trial-and-error, minimizes tool wear, and improves surface quality. This integration is especially beneficial when machining medium carbon steels like EN8, which are widely used in automotive and mechanical applications. The major problem addressed in this Research is the selection of optimal milling parameters to achieve high material removal rate with good surface finish and dimensional accuracy while reducing machining time and tool wear. CAM software is used for tool-path generation, machining simulation, and parameter optimization, as it allows virtual verification and efficient planning of CNC milling operations. The results achieved show that optimized spindle speed, feed rate, and depth of cut significantly improve surface finish, reduce machining time, and enhance overall machining efficiency for EN8 material.
