Abstract

Industrial robots have been used for welding, painting, assembling, and material handling where the required accuracy is usually not very crucial. For drilling processes in the aerospace industry where individual part accuracy and hole quality are important, today’s industrial robots have limitations. There are several difficulties in applying the robot to the drilling process. First, no available drilling machine is suitable for use by a robot. Second, the accuracy or rigidity of present industrial robots is not good enough for hole positioning and is not able to cope with the dynamics of the drilling process. Third, the cutting tool, i.e., drill bit, is subject to tool wear and breakage. At present, a commercially available drilling tool was fitted with the robot, but those existing drill tools were designed for use in manual operation and did not yield satisfactory results. Much effort was put into modifying and augmenting these drilling tools to improve their performance with robots. The knowledge gained in the modification of these manual drills has led us to conclude that a special end effector exclusively designed for robot application is necessary to meet all the needs of robot-controlled drilling.
