“…Advanced high strength steels (AHSS) machined by laser beam have applications in car industry and boiler works [26]. Titanium alloy sheets used in aerospace industry to make forward compression section in jet engines are cut by lasers [27][28][29]. Aluminium alloys used in aeronautics are one of the most promising for laser machining implantation [30].…”

“…An increase in cutting speed has the effect of reducing the extension of striations, roughness and dross height. B. Tirumala Rao, et al [9] presented work which aimed at studying the dynamic behavior of melt ejection in laser cutting of titanium sheet for obtaining dross-free cuts with minimum heat affected zone (HAZ). The results reveals use of He as the shear gas brought about significant reduction in dross formation.…”

Emergence of advanced engineering materials, stringent design requirements, intricate shape and unusual size of workpiece restrict the use of conventional machining methods. Laser Beam Machining (LBM) is one of the advance manufacturing processes which are used for shaping almost whole range of engineering materials. The present work deals with the study of varying pressure and traverse speed by CO 2 lasers for cutting the acrylic material and the attempt is made to develop a model to predict the depth of cut for 25 watt machine. The variation pattern for cutting depth is discussed about the convergence of predicted and experimental results.
