Abstract

Thesis reports are experiments related to the effects of parameters on laser machines using the taguchi method for raw materials are composites. This is because the composites have many advantages caused by high redundancy. Laser machining has been used for this study in composite product cutting methods based on the advantages this method can achieve. By conventional methods, the main limitation is the weakening of the surface. The proposed deduction as a method of improvement and design of the experiment (DoE) is used to approach this study. Furthermore,weaknesses have been found using conventional methods. An alternative way to use a laser machine is therefore recommended to solve the problems faced by manual cuts to achieve the goals stated in this study. This study consists of laser power, cutting speed, assisted gas pressure and focal distance. Quality reduction such as finished surfaces to determine laser cutting parameters. Parameters to get a good surface. The laser machine is a technology that uses lasers to cut material. For overall of this study the parameter when using laser machining that approximately 1500rpm is the optimum speed parameter which is nice. The nozzle gap result is 0.9 to 1.5. The closer the material nozzle, the easier it can be cut. It also depends on a high or low flow of gas as it will expand the cutting and cause burn mark. In general, there must be more information about running the machine and the process of laser cutting in order to challenge the student while doing the task. Next, takes too long to repeat the process parameters one by one to determine the optimal parameters.
