Abstract
A stringer manufacturing method for machining one end portion of an elongated member that is provided with a cap flange, a web, and a base flange and that has an inverted T-shape in a front view, an I-shape in a front view, or a T-shape in a front view into a desired shape to obtain a desired stringer. The one end portion of the elongated member is machined into a desired shape by using a vertical articulated robot (1) that has at least 6 axes and that has, at the tip of a valve unit (13), an abrasive nozzle assembly (14) that injects ultrahigh-pressure water containing abrasive and a catcher cup (15) that recovers the ultrahigh-pressure water ejected from the abrasive nozzle assembly (14).
