Abstract:
1. A method of removing burrs formed at a lower face of a plate-like work processed by a plate material processing machine, comprising: supporting a plate-like work on a work table in the plate material processing machine so that the plate-like work can be moved in X axis and Y axis directions; holding, by a work holding device and in a relatively movable manner, an upper face of the plate-like work near a processing edge of the plate-like work where the burrs form; and vibrating, when the plate-like work is moved relative to the work holding device in the X axis and Y axis directions, a striker provided to freely have an up-and-down motion in an up-and-down direction relative to the X axis and Y axis directions below the lower face of the plate-like work so that the burrs are removed by an upward motion of the striker.
