摘要： A manufacturing method of a three-dimensional object includes: a positioning step, an adhering step, a placing step, an additive manufacturing step, and a detaching step. In the positioning step, a fixing plate in which adhesive injection holes are formed is placed on a thin plate, and the thin plate is positioned on the fixing plate. In the adhering step, an adhesive is dripped to the adhesive injection holes, and the fixing plate is adhered to the thin plate. In the additive manufacturing step, a three-dimensional object in which the thin plate and a solidified layer are integrated is formed. In the detaching step, adhesion between the thin plate and the fixing plate is removed by a removing agent corresponding to the adhesive.

摘要： A stress controlled layer is constituted to include a compressive stress applied part that is a region to which a compressive stress is applied and a compressive stress non-applied part that is a region different from the compressive stress applied part. In a solidifying step, scanning of a laser beam or an electron beam is performed while a scanning direction for the compressive stress applied part is different from a scanning direction for the compressive stress non-applied part such that the compressive stress applied part expands further than the compressive stress non-applied part or the compressive stress non-applied part shrinks compared with the compressive stress applied part based on a relationship between the scanning direction and an expansion quantity or a shrinkage quantity at a time of temperature change or at a time of heat treatment.

摘要： The lamination molding apparatus includes an irradiator, a processing device, a cooling device, and an inert gas supply source. The irradiator irradiates a laser beam or an electron beam to a material layer to form a solidified layer. The processing device includes a processing head for holding a tool, and a processing head driver for moving the processing head in at least a horizontal direction. The cooling device is arranged in the processing head and cools a solidified body formed by laminating the solidified layers to a cooling temperature. The cooling device includes a cold gas discharger having a cold gas discharge port for discharging a cold gas being an inert gas having a temperature equal to or lower than the cooling temperature, and discharging the cold gas toward the solidified body. The inert gas supply source supplies the inert gas to the cold gas discharger.

摘要： An upper guide assembly includes an upper wire guide, an upper power feed contact, and a power feed contact movement device, and a lower guide assembly includes a lower power feed contact. The upper power feed contact and the lower power feed contact are configured to contact the wire electrode to supply power by moving in a horizontal direction from initial positions not contacting the wire electrode. The power feed contact movement device is configured to move the upper power feed contact in the horizontal direction from the initial position by a predetermined offset amount. The offset amount is set based on a machining condition including at least one of a condition of the wire electrode, a condition of a workpiece, and a surface roughness required for a cut surface of the workpiece.

摘要： A compact lower guide unit that allows the electrode guide to be attached and detached more easily and reliably. Provided is a lower guide unit including a housing, an electrode guide, and a pull-up mechanism having a guide support, links, and a power cylinder. The guide support includes a biasing member and a displacement member. The biasing member can bias the displacement member, and the displacement member can be displaced between a restriction position and a release position. The links can be rotated by a force applied by the power cylinder. The electrode guide is fixed to the guide support by a biasing force of the biasing member when the displacement member is in the restriction position, and the electrode guide is released from the lower guide unit when the displacement member is displaced to the release position.

摘要： To automatically change and set machining conditions suitable for a plate thickness even when machining paths of a rough machining step and an end surface finishing step are different in level difference machining in which the plate thickness changes during machining. In a wire electric discharge machining method and a wire electric discharge machining apparatus of the disclosure, an XY-plane of a workpiece stand is divided into small regions to form a plurality of divided regions, and a plate thickness of the workpiece is detected and stored in association with the divided regions. Thereafter, whether there is a level difference ahead of a traveling direction of a machining path is estimated according to plate thickness information associated with the divided regions and a plate thickness of the workpiece at a current machining position, and machining conditions are changed.
