Abstract

Recently, high-torque AC servomotors have been developed, and NC servo press machines equipped with these servomotors have started to become commercially available in Japan. The NC servo press machine has a programmable function to fully control the position and velocity of the slide on the machine. In this study, we experimentally examined the possibility of the burr-free shearing of an A5052 aluminum alloy sheet using such a press machine. As a result, it was clarified that burr-free shearing, which requires three processes using a conventional machining method, such as counter blanking, can be accomplished in one process using a common single-station die. The experiments also revealed that, when a punch or die, the edge of which is rounded with a radius range of 0.2-0.3 mm, is used, the range of conditions under which a sheared surface without burr generation can be obtained is wider than that for the case in which a sharp-edged tool is used.
