ADDITIVE MANUFACTURING APPARATUS, CONTROL METHOD THEREFOR, CONTROL PROGRAM, AND COMPOSITE PROCESSING APPARATUS

The invention provides an additive manufacturing apparatus, a control method thereof, a control program, and a combined machining apparatus. The additive manufacturing apparatus includes: a powder feeder configured to send out powder using a carrier gas; the head part is used for spraying powder; a first flow path for supplying powder from the powder feeder to the head; the flow path switching valve is arranged in the middle of the first flow path; a storage tank for receiving the powder fed from the powder feeder; and a second flow path connecting the flow path switching valve and the reserve tank and allowing the powder to flow from the powder supply machine to the reserve tank. The flow path switching valve can selectively supply the powder from the powder supply machine to the head or to the reserve tank. The first sensor is provided in the first flow path between the flow path switching valve and the head portion, and is configured to detect a first flow rate of the powder flowing to the head portion.
