It is a statistical approach in which a mathematical model is developed through experimental runs. DOE provides us the opportunity to optimize and predict possible output based on the parameters setting. In this study, a review is done on DOE techniques that have been employed for laser beam process optimization by other researches. This study predominantly focuses on the usage of response surface methodology, Taguchi's method and factorial design in laser beam machining. A deduction is made to illustrate the significance of machining parameters to responses. Index Term-Design of experiment, mathematical model, response surface methodology, Taguchi method, factorial design.

Grinding is the most common process when the workpiece demands good surface, dimensional and geometrical quality. In this experiment, the finding is the actual effect of surface roughness and the relationship for each parameter that have been choosing. The method that has been used to design the experiment was Design of Experiment (DOE) full factorial with two levels. The surface roughness of the workpiece has been analyzed by using a Portable Roughness Measurement Machine. The data will be compared and analyzed using MINITAB 14 software. The graphs have been created to shows the optimum factor and interaction between the factors. This experiment runs using three factors which are traverse speed, work speed and depth of cut.
