Parametric Influence Study for Laser Cutting on Acrylic

Laser has been employed for producing the complex specimens very efficiently and magnificently. The use of acrylic components is becoming prevalent day by day. Hence it is required to study the various machining techniques for engraving or cutting of acrylic material. The one of the non-traditional machining processes which can be employed efficiently for machining of acrylic is CO₂ laser machining. The parametric study of acrylic materials by using CO₂ laser machining is discussed in this paper. The scanning speed and the laser power were considered as process parameters and the influence of these parameters is studied on the depth as response measure. The engraving depth is observed to be increasing with increase in power and noted to be decreasing with increase in the scanning speed.
