Abstract—There are more than 1.3 million holes in a typical large aircraft. The drilling is made by a variety of processes. For components that cannot be mounted on a CNC machine, drilling is made on-site after the components are assembled together. Many efforts have led to the increasing use of robots and special tools for on-site drilling, but manual drilling is still often used. In this study, a simple drilling model was designed that can make holes in a similar procedure to manual drilling, without human assistance. The experiments focused on the drilling under conditions where the workpiece deflects during machining. In the proposed drilling method, the load P(N) applied to the cutting edge is the critical operating parameter for burr formation. The simple model had a suitable P that can suppress burr formation. To develop an automated tool based on the proposed method, it is necessary to identify the optimum control conditions for applied load P.

Keywords—drilling, burr formation, manual operation, thrust force, deflection
