| Summary: | The Aluminium alloy 7075 (AA7075) reinforced with nano Silicon Carbide particles (nSiCp) has attractive applications in aerospace, automobile, aircraft, turbine blades and electronics substrates because of its excellent properties such as strength, stiffness, corrosion resistance, wear properties and strength to weight ratio. These modern-day industries use conventional operations like drilling, milling to get the required shape and size in order to ease the assembly process. Whereas, the dimensional accuracy of the drilled hole without any defect is vital to ensure the strength of the joint. However, drilling the aluminium nanocomposite is quite challenging due to its heterogenic properties, which requires sufficient knowledge of selecting the appropriate machining parameter setting and high-end strategies to achieve good surface finish, superior hole quality and dimensional accuracy. However, the drilling process is mainly influenced by the quality of the machine, drill tool geometry, tool material, cutting velocity and feed rate. This research aims to investigate the machinability of the fabricated aluminium nanocomposite by conducting experimental drilling tests. In addition, a 3D Finite Element Model (3D FEM) was developed to simulate the drilling process for understanding the influence of machining parameters on critical thrust forces, chip formation, chip morphology, stress and hole quality. The experimental results agreed well with the 3D FEM simulation results in the correlation study, which ensures the accuracy and reliability of the developed 3D FEM. The study also recommends to use low feed rate and higher cutting velocity for reducing the critical thrust force during drilling. |
