| Summary: | 碩士 === 國立中興大學 === 機械工程學系 === 88 === As the technology that changes with each passing day, the punch press also has stepped into the new age of computerization and high-speed techniques. But it produces some problems of dynamic characteristic and positioning accuracy between each axis. Adjusting the parameters of the servo controller is the best way to get instant results without making changes in the design of mechanism when you face with such problem.
This research adopts Tailift HP-1500 CNC turret punch press equipped with FANUC-18PC controller as the subject. Besides, the circularity, suqareness error and servo coordination measuring by way of the Renishaw QC-10 Ballbar System are used as indicators to judge the performance of contour-accuracy. Taguchi Method is also adopted to probe into the parameters of servo controller that influence the performance of contour-accuracy in this research. In the meantime, to find out the key parameter and the best level combination, acquire a good match between the control system and the machine. It could be obtained the best performance and reached the goal of mechanical and electrical integration. Finally, the contour-error of the CNC punch press will be improved.
