Abstract: A clamp device includes: a tool spindle including a protrusion; an additive-manufacturing head having a recess into which the protrusion is inserted in a first direction, the additive-manufacturing head being detachably coupled to the tool spindle; and a clamp mechanism portion that clamps mutually the recess and the protrusion inserted into the recess. The additive-manufacturing head includes a pin member. A pin insertion hole into which the pin member is inserted in a second direction intersecting the first direction is made in the tool spindle.

Abstract: A processing machine includes a splash guard that defines and forms a processing area, a tool spindle that is movable in a Z-axis direction and a Y-axis direction inside the processing area, an additive-manufacturing head connected to the tool spindle, and a line body that extends from the additive-manufacturing head, is drawn from an inside of the processing area to an outside, and supplies material powder and a laser beam to the additive-manufacturing head. A maximum movement amount of the tool spindle in the Y-axis direction is shorter than a maximum movement amount of the tool spindle in the Z-axis direction. A drawing direction of the line body from the inside to the outside of the processing area is a direction intersecting the Z-axis direction in top view.

Abstract: A processing machine includes a splash guard, a tool spindle that is provided inside a processing area and holds a tool, and an automatic tool changer that is movable between an internal-side tool changing position inside the processing area and a standby position outside the processing area and changes the tool held by the tool spindle at the internal-side tool changing position. The splash guard includes a cover body that is coupled to the automatic tool changer, defines and forms the processing area when the automatic tool changer is positioned at the standby position, and enters the processing area when the automatic tool changer moves from the standby position to the internal-side tool changing position.

Abstract: A manufacturing machine includes: a tool spindle configured to hold a tool for subtractive manufacturing for a workpiece; an additive manufacturing head detachably mounted on the tool spindle to discharge material powder and emit a laser beam during additive manufacturing; and a head stocker storing the additive manufacturing head in an outside-of-machining-area. The additive manufacturing head includes: a head body into which a laser beam is introduced; and a laser tool detachably mounted on the head body to emit the laser beam and define a laser-beam-irradiated region on the workpiece. The manufacturing machine further includes: a laser tool stocker storing a plurality of laser tools; and a laser tool exchanger for exchanging laser tools between the head body and the laser tool stocker. A high productivity of additive manufacturing is achieved by using the above features configured in this way.

Abstract: A manufacturing machine is a manufacturing machine capable of additive manufacturing. The manufacturing machine includes: an additive-manufacturing head configured to be movable in a machining area and to discharge material powder toward a workpiece and irradiate the workpiece with an energy beam; and a powder chute configured to be movable in the machining area and to receive material powder discharged from the additive-manufacturing head toward the workpiece and failing to attach to the workpiece. There is provided the manufacturing machine configured in the above-described manner to be capable of efficiently collecting material powder having failed to attach to the workpiece during additive manufacturing.
