In this paper we describes slide-bending formation of thin metal sheet by using an industrial robot which has five degrees of freedom. The reactive force were meadured by a force sensor mounted on the robot and the bending angle og the metal sheet was measured by a CCD camera. The trajectory of the robot was controlled so that the reactive force was kept constant. From the results of the experiment, it is shown that The trajectory of the robot was controlled so that the reactive force was kept constant. The bending angle of the sheet was measured by the CCD camera. From the results of the experiment, it is shown that the bending angle of the thin metal sheet can be controlled by the applied load.
