Manufacturing machine

A manufacturing machine capable of subtractive manufacturing and additive manufacturing for a workpiece, the manufacturing machine comprising:

• a tool holder disposed movably in a machining area and configured to hold a tool to be used for subtractive manufacturing from a workpiece;
• an additive manufacturing head configured to be detachably mounted on the tool holder and to discharge material powder and emit an energy beam during additive manufacturing for a workpiece;
• a head stocker configured to store the additive manufacturing head on the outside of the machining area,
• the additive manufacturing head including
• a body into which an energy beam is to be introduced, and
• an emission part configured to be detachably mounted on the body and to emit the energy beam and define an energy-beam-irradiated region that is a region irradiated with the energy beam on the workpiece;
• an emission part stocker disposed on the outside of the machining area and configured to store a plurality of the emission parts that are different from each other in terms of the energy-beam-irradiated region defined on a workpiece;
• and
• an emission part exchanger configured to cause the emission parts to be exchanged between the body and the emission part stocker, wherein
• the tool holder is configured to be swivelable about a predetermined axis,
• a direction in which the emission part emits the energy beam is changed as the tool holder swivels, and
• when the emission parts are to be exchanged by the emission part exchanger, the tool holder is swiveled to position the additive manufacturing head in a posture that enables the emission parts to be exchanged between the body and the emission part stocker.

• a first cover including a first open-close member configured to be openable and closable, the first cover being configured to separate the inside from the outside of the machining area from one another;
• and
• a second cover including a second open-close member configured to be openable and closable, the second cover being configured to cover a plurality of the emission parts stored at the emission part stocker on the outside of the machining area.
