The dissertation is to study the factors affecting the quality of the hole in the process of drilling aluminum 6063 with design of experiments. Objective to study the factors that affect the quality of the hole. To study the error of the workpiece size and roundness. When the speed round. Feed rate and the angle drill drill speed and RPM in 909 1364, feed rate and drilling at 0.02 0.04 mm per round. Drill angle (Drilling Angle) and in 130 140 degrees. Apply design factorial design model 〖 2 〗 ^ k by experiment 2 level, and the experiment was repeated 2 times. In conclusion this test to the conclusion by studying from the comparison of the average error value of the round and the dimension of the target. Of the target and 16 pieces by measuring with a measured size work 3 dimensions.The test results from the process of punching aluminum 6063 with experimental design of the target.Factors significantly speeds. Will affect the size of the hole the most round speed 1364 rpm. The feed rate in drilling will affect the size of the hole the most level 0.02 mm per round. The factors will affect the angle drill hole size of most 130 angle degrees, which from the 3 factors showed that factors angle drill. Affecting the size of the hole more factors, speed and feed rates.The roundness of workpiece process from aluminum 6063 drill with experimental design of the target. The factors that will affect the speed of the most 1364 RPM speed. The factors. The feed rate in drilling will affect the value of the most 0.02 mm per round. And the factors to affect the roundness angle drill most corner 130 degrees, which 3 นี้พบ factors from both the factors affecting the speed value more factors. Feed rate and angle flower mohair.
