Abstract

Laser beam machining (LBM) is a cutting-edge technique widely utilized for precision machining of advanced materials. This experimental investigation focuses on the surface roughness of aluminum alloy (Al 6061) during LBM. The study systematically examines the impact of process parameters such as laser power, cutting speed, and gas pressure on surface roughness (Ra). The significance of surface roughness in determining the quality and functionality of machined components is emphasized. The experimental setup employs the AMADA LCG3015AJ laser beam machining system with a 6000W fiber laser, ensuring precision and control over various parameters. A factorial design matrix, incorporating factors like laser power and scanning speed, is strategically employed. Response Surface Methodology (RSM) aids in constructing a predictive model for surface roughness, facilitating optimal conditions for desired finishes. The experimental runs, conducted at M/s Anand Lasers, Pune, India, involve the systematic alteration of parameters, and surface roughness is evaluated using advanced metrology methods. Statistical analysis, including ANOVA, unveils significant contributors to surface roughness, guiding process optimization. The final expression incorporating coded factors provides a comprehensive understanding of the relationship between process parameters and surface roughness. The results showcase the intricate dynamics of LBM on aluminum alloy surfaces. The study contributes valuable insights for optimizing machining processes, enhancing surface quality, and advancing precision manufacturing.

Keywords: Surface roughness, aluminium alloy, laser beam machining, Anova, alloy, thermal analysis, characterization, processing and manufacturing, properties and performance, mechanical properties.
