This research is to find the optimal parameters of machining process. The research conduct based on Design of Experiment DOE analysis. In this research the experiment designed to find out the interaction between the variables to evaluate the high performance responses of machining process. The experiment is design based on the objectives that want to be achieved in this research. The analysis is run by using the Minitab Software. In this research, Response Surface Methodology and factorial design used to compared in term of modeling capabilities. The input parameters evaluated were gas pressure, power supply, and cutting speed; meanwhile the output responses being kerf width and surface roughness. The laser cutting process is one of the widely used techniques for cut various thickness of material for many applications such as fiber, steel, wood etc. In the area cutting material, it can be improved drastically with the application of difficult cutting material. Application of cut on mild steel for various machining techniques, such as bevel linear and bevel non-linear cutting, requires different cut characteristics. From that, being highly dependent on the process parameters under which they were performed. To efficiently optimise and customise the kerf width and surface roughness characteristics, machining of laser cutting conduct via modelling using RSM methodology was proposed. In this research, non-linear incline cutting is done on critical laser processing of mild steel materials optimization . This research predominantly focuses to investigate the correlation between laser machining parameter with the responses kerf width and surface roughness. This research also highlights the experimental control parameters of mild steel laser processing with the responses.
