dc.description.abstract In this paper, we investigate the effect of CO2 laser machining on wood, perspex and glass. These materials are very important due to their wide applications and thus there is need to machine them as desired. Glass is a hard, optically transparent and used for a variety of purposes such as eyewear, bottles, windows and even certain types of furniture. Perspex is the clear, light weighted, hard and thick plastic, widely used for watch glasses, advertising signs, domestic baths, motorboat windscreens, aircraft canopies, and protective shields. To eliminate the possibility of the CO2 light being diffused by dirt/dust particles on the surface of these materials being experimented on, thorough cleaning of the surfaces is done and these specimens left to dry before use. A continuous wave (cw) CO2 laser beam with an estimated power of 35 Watts is then focused on the surfaces of the specimens. Machining time and the number of scans are varied and their effect on depth, hole diameters, kerf widths, taper, aspect ratio and heat-affected-zone (HAZ) investigated. Effect of compressed air as the assist gas on hole profiles and the point at which glass cracks was also investigated. During these experiments, the machining velocity, laser and optics parameters were kept constant. Results showed that in an increase in the input parameters resulted in an increase in the features under investigation. en_US
