Abstract

Atomic force microscopy (AFM) is a kind of scanning probe microscopy which results in precise and accurate 2D and 3D images for examining surface topography and morphology in quantitative and qualitative terms. The main objective of this research is to characterize the surface integrity of machined samples by employing atomic force microscopy (AFM). The secondary aim is to accomplish statistical analysis of surface roughness based on different sets of machining parameters. In the current research, Taguchi’s L16 orthogonal arrays are adopted, and sixteen numbers of Ti6Al4V samples have been produced by utilizing the wire electrical discharge machining (WEDM). A comparison has also been made by probing the surface topographies, cross-sectional profiles, and roughness graphs to confirm the influence of machining parameters on the surface quality of machined samples. Through statistical analysis, the cutting voltage is found the most significant machining variable which influences the response variable.
