This thesis is the study of factors that affect the quality of drilling hole drilling process in aluminum. 6063 with design of experiments The objective is to study the factors that affect the quality of education for tolerance of drilled hole size and workpiece roundness value. When assigning a speed drill and drill by mumdok rate entered is located at 909 speed and RPM 1364. The rate of penetration is at 0.02 and 0.04 enter millimeters per round mumdok drill (Drilling Angle) is located at 140 degrees and 130 design experiments a factorial 〗 〖 2 ^ k model by level-2 trial and repeat 2 times tried to summarize the test results, once this is done, the conclusion by studies from the comparison of the average of the tolerance value, the size of the work piece and round of 16 pieces, both by measuring with 3D measuring machines. Test results from a 6063 aluminum penetration process by the experimental design of the workpiece. Found that the speed factor will affect the size of the hole that the no-load speed RPM factor section 1364. Enter a rate in the drilling will affect the value of the size of the hole is the most level of 0.02 mm per round drill mumdok factors will affect the value of the size of the hole drilled at an angle of at most 130 degrees, from which all three factors found that this factor mumdok Auger. Affect the value, the size of the hole rather than factors. Speed and feed rates The value of the workpiece roundness from a 6063 aluminum penetration process by the experimental design of the workpiece. Speed factors are found to affect the roundness value most no-load speed RPM factor section 1364. Enter a rate in the drilling will affect the roundness value 0.02 millimeters at most per round and drill mumdok factors will affect its value most from 130 degrees angle at which all this factors. Find that speed factors affect the rate at factors enter the klommakkwa value and the mumdok ROMs.
