There are many papers that deal with the edge quality of mild steel that has been cut by a CO_2 laser. Most of these papers, however, refer to a thin plate, less than 6mm thick. For plates thicker than 9mm, as the cutting speed decreases, the difference between the cutting speed and the oxidizing reaction speed Produces an even rougher edge. Therefore, CO_2 laser cutting cannot provide versatility over a wide range of thick plate applications. This study deals with improving the edge quality of mild steel 12mm thick. Using high-frequency, low-duty pulses the groove size produced by the oxidizing reaction is reduced. Moreover, a beam energy of higher peak power can be transmitted through a greater thickness than possible during CW cutting. As a result, the pitch of the grooves generated on the cut edge is reduced, and the edge quality is greatly improved.
