Abstract

A manufacturing machine is capable of subtractive manufacturing and additive manufacturing for a workpiece. The manufacturing machine includes: a first headstock and a second headstock disposed in a first processing area and configured to hold a workpiece; a lower tool rest and a tool spindle disposed in the first processing area and configured to hold a tool to be used for subtractive manufacturing for the workpiece; an additive manufacturing head disposed in a second processing area; and a robot arm configured to hold a workpiece and transport the workpiece between the first processing area and the second processing area. The additive manufacturing head is configured to discharge a material toward the workpiece held by the robot arm during additive manufacturing for the workpiece. Accordingly, the manufacturing machine configured simply to be capable of subtractive manufacturing and additive manufacturing is provided.

First claim

The invention claimed is:

1. A manufacturing machine capable of subtractive manufacturing and additive manufacturing for a workpiece, the manufacturing machine comprising:
a cover defining each of a first processing area and a second processing area;
a workpiece holder disposed in the first processing area and configured to hold a workpiece;
a tool holder disposed in the first processing area and configured to hold a tool to be used for subtractive manufacturing for the workpiece;
an additive manufacturing head disposed in the second processing area; and
a manipulator configured to hold a workpiece and transport the workpiece between the first processing area and the second processing area,
the cover including a partition separating the first processing area and the second processing area from each other,
the additive manufacturing head being configured to discharge a material toward the workpiece held by the manipulator during additive manufacturing for the workpiece,
the workpiece holder being configured to hold the workpiece in only the first processing area of the first processing area and the second processing area,
during subtractive manufacturing for the workpiece, the workpiece holder holding the workpiece in the first processing area and the manipulator being withdrawn from the first processing area into the second processing area, and
during additive manufacturing for the workpiece, the workpiece holder being positioned in the first processing area and the manipulator holding the workpiece in the second processing area.

2. The manufacturing machine according to claim 1 , further comprising:
an inert gas feeder configured to feed an inert gas to the second processing area
wherein the cover defines the second processing area as a substantially sealed space.

3. The manufacturing machine according to claim 1 , wherein
the manipulator is a robot arm having multiple axes that are controllable, the robot arm including a movement mechanism configured to be movable between the first processing area and the second processing area.

4. The manufacturing machine according to claim 2 , wherein
the manipulator is a robot arm having multiple axes that are controllable, the robot arm including a movement mechanism configured to be movable between the first processing area and the second processing area.
