Abstract

Laser Beam Machining is widely used manufacturing technique utilized to perform cutting, engraving and welding operations on a wide variety of materials ranging from metals to plastics. In the present work an attempt has been made to study the effect of process parameters such as feed rate, input power and standoff distance on the quality of the machined surface using Carbon dioxide (CO2) laser beam on 3 mm thick mild steel sheets. The quality of cut is assessed in terms of response parameters such as upper kerf width, lower kerf width, taper of the cut surface and surface roughness. Design of experiments was implemented by using a full factorial design. The effect of the process parameters on response have been shown by means of main effect plots developed using statistical software. It was found that upper kerf width decreased with increase in feed rate and increased with increase in laser power. Surface roughness of the cut decreases with increase in feed rate and power.
