摘要： An additive manufacturing apparatus produces a shaped article by adding a material melted by emission of a beam, to a workpiece. The additive manufacturing apparatus includes a machining head that emits the beam to the workpiece, a feed unit that feeds the material to the workpiece, and a numerical control device, which is a control unit that determines a machining path along which the machining head is caused to move with respect to the workpiece, and outputs a command to move the machining head. The control unit outputs a command to move the machining head along the machining path obtained by correction performed based on a moving direction of the machining head with respect to the workpiece.
