Additive manufacturing apparatus, additive manufacturing system, additive manufacturing method, storage medium, and learning device

An additive manufacturing system comprising:

• an additive manufacturing apparatus to produce a shaped article by adding, to a workpiece, a material melted by emission of a beam;
• and
• a machining program generation device to generate a machining program based on geometrical data of the shaped article, wherein
• the additive manufacturing apparatus includes
• a machining head to emit the beam to the workpiece,
• a feed unit to feed the material to a melt pool formed on the workpiece by the emission of the beam, and
• control circuitry to determine, by analysis of the machining program, a machining path along which the machining head is caused to move with respect to the workpiece, and to output a command to move the machining head, and
• the control circuitry 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, the correction being made for a positional deviation of the melt pool caused by a bias in an energy distribution due to an effect of a shape of a spot of the beam on the workpiece and to an effect of the moving direction.
