Objectives: This machining method has been magnificently employed in machining various materials, starting from aluminum, a highly ductile material, to very hard materials like ceramics and Inconel’s. Inconel and Ti-based alloys have a treasure trove of wider applications in these present industries. Methods: In this investigation, an effort is made to study the influence of LBM input parameters such as laser power, machining speed, and gas presser on Inconel 825 plates, both linear and nonlinear. Statistical Analysis: Preliminary trials were conducted by changing the process parameters in order to design a process parameter window. Findings: The design matrix has been developed with L9 experiments, and the corresponding outputs and responses, such as kerf width and surface roughness, were measured and recorded. Applications: The responses have been used to measure the Ra and kerf values of all the specimens after being cut by LBM. Improvements: ANOVA identifies the influencing process parameters on machining Inconel 825 output responses, namely kerf width and surface roughness. Keywords: Laser Beam Machining, Inconel825, Kerf Width, ANOVA, Surface Roughness. 1. Introduction Metal cutting using lasers is the more trustworthy technology for the fabrication of engineering products. Laser beam machining (LBM) is widely used for producing complex profiles in almost all materials (Sharma & Yadava 2010). The viable application of lasers involves varying fields like medical, industrial, army, and scientific research [1]. The classification of lasing media into solid, liquid, or gaseous categories is determined by their respective wavelengths[2]. The commercially available lasers for material processing in industries encompass a variety of types, including Ruby, Nd-Glass, Diode, He-Ne (Helium-Neon), CO2 (Carbon Dioxide), Nd- * K.
