Abstract

A manufacturing machine is capable of additive manufacturing. The manufacturing machine includes: a connecting part configured to be connectable to a machine tool capable of subtractive manufacturing; and an additive manufacturing head configured to be positioned in a machining area of the machine tool and discharge a material, when the connecting part is connected to the machine tool. The manufacturing machine for additive manufacturing that can be installed at a low cost is thus provided.

First claim

1 . A manufacturing machine capable of additive manufacturing, the manufacturing machine comprising:
a connecting part configured to be connectable to a machine tool capable of subtractive manufacturing; and an additive manufacturing head configured to be positioned in a machining area of the machine tool and discharge a material, when the connecting part is connected to the machine tool.

2 . The manufacturing machine according to claim 1 , wherein
the additive manufacturing head enters the machining area through an opening of the machine tool formed by opening a door of the machine tool.

3 . The manufacturing machine according to claim 1 , further comprising an electrical connector configured to be connected to the machine tool for transmitting, from the machine tool, a control signal for the additive manufacturing head, when the connecting part is connected to the machine tool.

4 . The manufacturing machine according to claim 1 , further comprising a head drive mechanism configured to move the additive manufacturing head three-dimensionally.

5 . The manufacturing machine according to claim 1 , further comprising a height adjustment mechanism configured to change a height of the connecting part.

6 . The manufacturing machine according to claim 1 , wherein
the additive manufacturing head is configured to perform additive manufacturing by discharging material powder and emitting a laser beam to a workpiece, and the manufacturing machine further comprises: a dolly on which the connecting part and the additive manufacturing head are mounted; a material powder feeder mounted on the dolly and configured to feed material powder to the additive manufacturing head; and a laser oscillator mounted on the dolly and configured to generate a laser beam to be emitted to a workpiece.

7 . The manufacturing machine according to claim 6 , wherein
the additive manufacturing head is configured to discharge an inert gas to the workpiece when discharging the material powder and emitting the laser beam to the workpiece, and the manufacturing machine further comprises: an inert gas feeder serving as a source of an inert gas to be discharged to the workpiece; and an environmental measurement device configured to measure an environment in the machining area of the machine tool.

8 . A manufacturing machine capable of a first additive manufacturing, the manufacturing machine comprising:
a connecting part configured to be connectable to an additive manufacturing machine capable of a second additive manufacturing different in type from the first additive manufacturing; an additive manufacturing head configured to be positioned in a machining area of the additive manufacturing machine and perform the first additive manufacturing by discharging material powder and emitting a laser beam to a workpiece, when the connecting part is connected to the additive manufacturing machine; a material powder feeder configured to feed material powder to the additive manufacturing head; and a laser oscillator configured to generate a laser beam to be emitted to a workpiece.
