Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications. Laser cutting works by directing the output of a high power laser, by computer, at the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high quality surface finish. This study is focusing on CO2 laser cutting process on Polypropylene (PP) polymer. By cutting this type of polymer, the quality of cutting surface is evaluated. Through this study, the parameters that involved in laser cutting are examined. The laser parametric that affects the result and machining characteristic of surface roughness on the cutting surface will be studied. There are three parameters that want to be evaluated in this experimental study, which are the cutting speed, focal length of the lens, and gas pressure. A two-level full factorial is used to examine the combinations of these three parameters during the experiment. Two levels full factorial design means, there are two levels (high and low) of the value of each parameters that will be used in this process. Through this experimental study, there is only one response that will be evaluated, which is surface roughness, Ra. The value of Ra will be determined by using portable roughness measuring machine. Then, the result will be generated by using Minitab v14 software by entering all the measurements data and some graph will be plotted in order to find the main effect which is significant. From these three parameters, the factors that gives the main effect in cutting quality will be determined. This result will be used to find the suitable values or level combination to produce the good quality in laser cutting.
