| Abstract: The aim of the present research is to study the role of nozzle and the effect of the stand –off distance which are the most important parameters for cutting mild steel by "CO2 laser – gas jet . Relationship between the laser power and stand-off distance of nozzle at different cutting speed and thicknesses were achieved. It was found that the power increases with cutting speed for particular stand-off distance. In addition , the laser power proportional with stand-off distance for low cutting speed but out the proportionality at high cutting speed . However, the results of this study are necessary in order to move another step towards understanding and to clarify their benefits for cutting process by laser | ||
