A chemical oxygen-iodine laser (COIL) was used for cutting aluminum and carbon steel. Cut depths of 20 mm were obtained in aluminum and 41 mm in carbon steel using an N 2 gas assist and 5-6 kW of power on target. The same laser at the same power level produced a cut depth of 65 mm in carbon steel with an O 2 gas assist; a low quality cut to a depth of nearly 100 mm in carbon steel was demonstrated. These data are compared with existing COIL and CO 2 laser cutting data. COIL cuts carbon steel and stainless steel at approximately the same rate. For a given cut depth, power and spot size, COIL cuts steel approximately three times faster than a CO 2 laser using an inert gas assist. COIL cutting speeds in carbon steel are improved by approximately a factor of three when an O 2 assist is used in lieu of an N 2 gas assist. With an N 2 gas assist, COIL cuts aluminum at approximately the same rate as CO 2 cuts steel. To improve the agreement between data and an existing theoretical cutting model, an empirical correction factor was added to the model; this modification provides excellent agreement with data.

Cut depths of 20 mm were obtained in aluminum and 41 mm in carbon steel using an N2 gas assist and 5-6 kW of power on target. The same laser at the same power level produced a cut depth of 65 mm in carbon steel with an 02 gas assist; a low quality cut to adepth cf nearly 100 mm in carbon steel was demonstrated. These data are compared with existing COIL and CO2 laser cutting data. COIL cuts carbon steel and stainless steel at approximately the same rate. For a given cut depth, power and spot size, COIL cuts steel approximately three times faster than a CO2 laser using an inert gas assist. COIL cutting speeds in carbon steel are improved by approximately a factor ofthree when an 02 assist is used in lieu of an N2 gas assist. With an N2 gas assist, COIL cuts aluminum at approximately the same rate as CO2 cuts steel. To improve the agreement between data and an existing theoretical cutting model, an empirical correction factor was added to the model; this modification provides excellent agreement with data.Recently, COIL cutting data has appeared in the literature. Atsuta et al.16 obtained the first results for cutting stainless steel which were quite promising. Kar et al.17 produced a more complete data base for stainless steel cutting with an inert gas assist. This work extends the COIL cutting data base to include data for cutting aluminum and carbon steel with 758 SPIE Vol. 3092 • 0277-786X/971$10.00 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/23/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx
