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.
