A method of removing partially sintered powder from an internal passage in a metal component formed by electron beam additive manufacturing (EBAM) includes co-forming a solid wire cutter in the passage during the EBAM forming process and removing partially sintered powder from the cavity by extracting the cutter from the cavity.

A method of making a part including a solid portion with an internal passage includes building the part using an additive manufacturing process that builds the part on a layer-by-layer basis. The solid portion of the part is formed. Forming the solid portion includes fusing the solid portion. A solid core is formed within at least a portion of the internal passage. Forming the solid core includes fusing the solid core and forming an attachment feature on the solid core. Material that is not fused, either semi-sintered or un-sintered, is positioned between the solid portion and the solid core. At least a tensile, compressive, vibratory, or torsional force is applied to the solid core at the attachment feature. The solid core is then removed from the part.

A winder unit is provided for use with cutting wire in cutting out a vehicle glazing panel. The winder unit includes first and second winder spools spaced apart from one another, where the winder spools are configured to wind the cutting wire. The winder unit further includes a suction mount for mounting the winder unit, wherein the suction mount comprises a single suction device only. And the winder unit further includes at least one wire guide element spaced from the winder spools, wherein the at least one wire guide element is mounted with respect to the winder unit so as to be adjustable in position or orientation with respect to at least one of the suction mount and the winder spools.

A portioning device is provided for use in cutting or leveling a food product. The portioning device comprises a handle section that is configured to be manipulated by a user, a leg section and a blade. The handle section includes an arm configured to receive a leg, a sleeve configured to slide over a portion of the arm, and an arm connector pivotally coupled to the arm. The leg section is configured to support the portioning device on a surface. The leg section includes a blade holder configured to hold an end of a blade portion, and a leg lock configured to adjustably lock the leg in a position. The blade is configured to cut an object.

A solar panel cutting unit according to an embodiment can separate layers of a solar panel from each other at once. The solar panel cutting unit separates thin layers of a solar panel from each other and includes a frame, a panel transporting mechanism that is provided at the frame and lowers the solar panel in a vertical direction such that adhesion lines of the thin layers are arranged downward, a pair of guide roller units that is positioned below the panel transporting mechanism and guides and lowers the solar panel, and a wire cutting mechanism that includes a pair of support rollers and cutting wires which connect the support rollers to each other and extend in the same direction as the adhesion lines such that the wire cutting mechanism separates the thin layers of the solar panel from each other.
