Comprehensive Analysis of Laser Processing Parameters on SS304 Steel: Experimental and Mathematical Insights

This paper presents an experimental and mathematical analysis of the laser process parameters by experimenting on a steel material, SS304, which was cut to the proper dimensions, and then a laser beam was passed through at varying velocities in the conditions when focal length, f = 0 and f = 5 mm. An inspection was done under an optical microscope after mirror polishing the cross-section of the workpiece. The diameter and depth of the beam can be observed, among other things. In the mathematical part, laser characteristics such as focal points like interaction time, power density, energy density, line energy, etc. are calculated. The graph is plotted, like interaction time versus depth of cut, interaction time versus beam diameter, etc., to study the behaviors of laser process parameters. the conduction at a focal length of 5 mm and keyhole at a focal length of 0 mm phenomenon was observed.
