Abstract: An optical processing head that detects a trouble of an optical processing head that will be generated at the time of optical processing before the trouble occurs is disclosed. The optical processing head that performs processing by condensing, on a process surface, a ray emitted by a light source for processing includes a cylindrical housing that surrounds a ray for processing emitted by the light source for processing, a ray emitter for inspection that is incorporated in the cylindrical housing and arranged outside the path of the ray for processing, and a light receiver that is incorporated in the cylindrical housing, arranged outside the path of the ray for processing, and receives a ray for inspection emitted by the ray emitter for inspection. The contamination of the inner surface of the cylindrical housing or the concentration of a scattering object flowing into the cylindrical housing is inspected by using a signal acquired from the light receiver.

Abstract: A machining apparatus that need not exchange a processing nozzle when changing a shaping condition, and increases the use efficiency of a material. The processing nozzle that performs processing by ejecting a processing material towards 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. The processing nozzle also includes 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. The processing nozzle also includes a slide mechanism that changes, along the energy line, the relative position of the outer housing with respect to the inner housing.

Abstract: An optical processing head capable of downsizing an apparatus while increasing the shaping accuracy of optical processing is disclosed. The optical processing head performs processing while moving, in a predetermined moving direction on a processing surface, an optical spot formed by condensing light emitted by a light source. The optical processing head includes an optical element that condenses light emitted by the light source to generate the optical spot of a shape elongated in the moving direction of the optical spot. Part of the optical spot is set as a processing region, the front side and/or rear side of the processing region in the moving direction is set as a pre-heating region and/or post-heating region, and a processing target object before and/or after processing in the region is heated.

Abstract: Ejection and stop of a powder flow are switched while maintaining a once generated steady flow without stopping it. A processing nozzle includes a supply source of a fluid containing a powder, a first channel through which the fluid supplied from the supply source passes, a second channel that supplies the fluid to an ejection port of the nozzle, a third channel that releases the fluid outside the nozzle, and a switch that causes the first channel and the second channel to communicate with each other when supplying the fluid to the ejection port, and causes the first channel and the third channel to communicate with each other when not supplying the fluid to the ejection port.

Abstract: An optical processing head capable of reducing the energy loss at the time of optical processing is disclosed. The optical processing head includes a first optical element that converts light emitted by a light source into first parallel light, a second optical element that is arranged downstream of the first optical element and converts the first parallel light into first divergent light, a third optical element that is arranged downstream of the second optical element and converts the first divergent light into second parallel light, and a fourth optical element that is arranged downstream of the third optical element and converts the second parallel light into convergent light which is condensed on the processing surface side.

Abstract: An optical processing nozzle that homogeneously supplies a fluid to a processing surface in optical processing. The optical processing nozzle includes a beam path that is arranged so that a beam can pass through the beam path towards a processing surface in order to perform processing using a beam guided from a light source, and a channel structure that is arranged around the beam path and is configured to eject a fluid towards the processing surface. The channel structure includes an inflow port through which the fluid flows, at least two passage holes through which the fluid flowing from the inflow port passes, a channel that guides the fluid from the inflow port to the passage holes, and an ejection port from which the fluid having passed through the at least two passage holes is ejected toward the processing surface.

Abstract: This specification discloses an optical processing head including a light guide portion that guides, to a process surface, a ray for processing. The light guide portion is further configured to guide, to the process surface, a ray for inspection different in wavelength from the ray for processing. The optical processing head further includes an inspection portion that inspects the state of the process surface based on reflected light of the ray for inspection reflected by the process surface. With the optical processing head, the state of the process surface can be easily inspected even during optical processing.
