Comparative Machinability Study: Aluminum and 316 Stainless Steel

This technical research paper presents a comparative machinability analysis of aluminum and 316 stainless steel, focusing on experimental investigations performed in a practical setting. The study examines the machinability of these two materials using drilling and milling operations, detailing the experimental setup, including CNC machine parameters such as cutting speed, feed rate, and depth of cut. The report analyzes chip formation, tool wear, and surface roughness using optical surface profilers to assess the impact of machining on the material properties. Additionally, it includes the calculation of frictional forces. The paper discusses the experimental details, analysis of the results, and concludes with a comparison of the machinability characteristics of aluminum and stainless steel under the specified machining conditions. The findings provide insights into the influence of different machining parameters on the material removal process and the quality of the machined surfaces.
