Optimization of Drilling Parameters for Aluminium Alloy to Minimize Ovality and Surface Roughness Using a Multi-Objective Approach

mechanical engineering

One of the major obstacles in the drilling process is choosing the right drilling settings. These days, quality and productivity can be maintained and increased through the use of optimization techniques. Aluminum alloys are used in about half of the world's industrial and commercial processes. Due of their great excellent ductility, strength, and limited heat conductivity, materials like austenitic stainless steel are difficult to manufacture. The experimental investigation of the performance features of the AA6101 T6 aluminum alloy while drilling will be covered in this paper. Performance metrics like ovality and surface roughness during the drilling process are influenced by variables including drill bit diameter, spindle speed, and feed rate. The ideal level of variables must be chosen carefully to accomplish the lowest possible ovality and surface roughness. This paper presents the optimization of multi-objective parameters in aluminum alloy drilling to achieve minimal ovality and surface roughness using Grey Relational Analysis. The experiments will be performed in accordance with the experiment design. Minitab17 is a statistical program used to collect and analyze the experiment findings.
