This research aims To determine the effectiveness of the drill hole and two-axis control with PLC tool used in the study consisted of. Air Drill hole 2-axis control with PLC Record the test drilling on the job. And assess the efficiency of the 5 experts in the research. Researchers have created and tested for effectiveness. Air Drill hole 2-axis control with PLC by the efficiency of the drill hole was drilled between two fingers and drag two fingers two inches apart. Worksheets Worksheets tested by 3 times and then the results were analyzed to determine the correct air drill hole 2-axis control with PLC test results must be accurate and complete. Then, 5 experts with knowledge and experience in the performance of the drill holes in two axes controlled by the PLC evaluated three aspects: 1. Structure 2. 3. The devices use a one expert. with an average of 4.90, which is good. The two experts with an average of 4.60, which is in very good shape. The three experts with an average of 4.50, which is in very good shape at 4 with an average of 3.90, which is in good shape at five with an average of 4.00, which is good. And the researchers analyzed the results of the evaluation of the quality of air drill hole 2-axis control with PLC of experts both of whom 5 with an average of 4.38 and standard deviation of the total value of 0.53 indicates that the quality of the drill. True two-axis control with PLC level was satisfactory. According to the hypothesis set.
