Abstract
Laser cutting is a difficult cutting process involves a coherent model for forecast of the process execution. The primary purpose of this study was to examine the influence of cutting condition on Top Kerf width and Bottom Kerf Width while CO2 laser cutting of AISI 316L.The input factors considered was the laser power, cutting speed, gas pressure and Thickness of work material. Design of experiment approaches was implemented by using box-Behenken design to make the experiment lay-out. Top Kerf Width and Bottom Kerf Width model for laser cutting were built using Response Surface Methodology, The modified to reduced cubic model have the best agreement with experimental data, and also the Thickness of work material plays a substantial role in achieving to minimize the kerf width.
