Abstract
A processing machine includes a laser irradiation device that emits an annular laser beam, and a wire feeding device that feeds a wire from an inside of the annular laser beam. When a workpiece irradiation proportion parameter (WIP) represented by an equation WIP=P/P (P: laser beam power introduced onto a workpiece surface when the wire exists in an irradiation region of the laser beam, P: the laser beam power introduced onto the workpiece surface when the wire does not exist in the irradiation region) is defined, a control device controls the wire feeding device so that a wire end abuts on the workpiece surface at a beginning of additive manufacturing. The control device determines initial power Pbased on the WIP at the beginning of the additive manufacturing, and controls the laser irradiation device so that the workpiece is irradiated with the laser beam at the initial power P.
