MACHINING NOZZLE, MACHINING HEAD, MACHINING EQUIPMENT, AND METHOD AND PROGRAM FOR CONTROLLING MACHINING NOZZLE

摘要

A machining apparatus that need not exchange a processing nozzle when changing a shaping condition, and increases the use efficiency of a material is disclosed. The processing nozzle that performs processing by ejecting a processing material toward a molten pool formed on a process surface by an energy line includes a cylindrical inner housing that incorporates a path through which the energy line passes, and ejects the energy line from one end, a cylindrical outer housing that incorporates the inner housing, and has an inner surface tapered in the ejection direction of the energy line ejected from the inner housing, and a slide mechanism that changes, along the energy line, the relative position of the outer housing with respect to the inner housing. The gap between the outer surface of the inner housing and the inner surface of the outer housing forms an ejection port for the processing material, and the size of the ejection port changes in accordance with a change of the relative position by the slide mechanism.
