摘要： A method of manufacturing a last chance screen for an aircraft engine includes forming an array of holes through a metal sheet with a wire electrode using electrical discharge machining. The array of holes comprises a plurality of holes. Each hole of the plurality of holes comprises a first end and a second end and is surrounded by a wall section such that the last chance screen is defined by the plurality of holes and the plurality of wall sections. The first and second end of each hole are widened by either applying a flow of an abrasive flow medium to the array of holes in two directions or using a conical sinker electrode on either side of the metal sheet. Shaping the first and second end of each hole results in an airfoil-shaped cross-section of each wall section.

摘要： The invention relates to a wire electrode for spark-erosion cutting, comprising a core (2), which has a metal or a metal alloy, and a sheath (3, 4, 6), which surrounds the core (2) and comprises one or more sheath layers (3, 4, 6), one of which comprises regions (3) having a morphology corresponding to block-like particles, which are spatially separated, at least over part of their periphery, from one another, from the material of the layer comprising said regions, from the material of one or more other layers and/or from the core material by cracks, characterized in that, in a wire cross-section, viewed perpendicularly or parallel to the wire longitudinal axis, more than 50% of the surface area of a region having the morphology of a block-like particle has a copper-zinc alloy with a zinc concentration of 38 to 49 wt. %. There is optionally a thin cover layer on the block-like particles, which cover layer consists of more than 50 wt. % zinc oxide with a thickness of 0.05 to 2 μm. Said cover layer has regions in which the copper-zinc alloys that the block-like particles have emerge at the surface. The invention also relates to a method for producing said wire electrode.

摘要： A method and device for removing an electromagnetic core, the method including: using an electromagnet to magnetize or demagnetize a metallic upper nozzle when a magneto-conductive workpiece is cut off in a WEDM manner; attracting a core capable of being completely cut off and separated in the workpiece; utilizing the metallic upper nozzle to detect whether attracted; if the core is attracted, moving the core to a target area; demagnetizing and dropping the core in a trash area. The device is applied to a WEDM machine; after the metallic magneto-conductive upper nozzle is magnetized by the electromagnet, the upper nozzle is used to attract the magneto-conductive core; a metallic water spray cover is utilized to detect whether the core is attracted; the core is moved to the target area by a motion system of the WEDM machine, and dropped in a trash device after the upper nozzle is demagnetized.

摘要： A wire electric discharge machine for machining a workpiece by causing a discharge between a wire electrode delivered from a wire bobbin and the workpiece. The wire electric discharge machine includes: a remaining length calculation unit that calculates a remaining length of the wire electrode based on electrode winding coefficients, bobbin draw-out radius correlation information, and a spool diameter of the wire bobbin. The electrode winding coefficients depend on a winding density of the wire electrode, an inner width of the wire bobbin, a wire diameter of the electrode wire, and a winding tension of the wire electrode. The bobbin draw-out radius correlation information is correlated with a bobbin draw-out radius that is a distance between a position at which the wire electrode wound around the wire bobbin is separated from the wire bobbin and a central axis of rotation of the wire bobbin.

摘要： An electrical discharge machining electrode wire includes a core including a copper or a copper alloy, and a covering layer covering a periphery of the core and including a zinc. The covering layer includes an inner layer including a γ-phase of copper-zinc based alloy and covering the periphery of the core, and an outer layer including an ε-phase of copper-zinc based alloy and covering a periphery of the inner layer. An x-ray diffraction intensity of (0001) of the ε-phase is more than twice an x-ray diffraction intensity of (332) of the γ-phase.

摘要： In a fixing structure and fixing method of a wire bobbin, the wire bobbin is abutted against the regulating member with the bolt inserted into the insertion hole of the wire bobbin. Then, a nut is inserted into a through hole while being kept inclined so that the axis of the through hole is substantially aligned with the axis of the bolt. Thereafter, the inclination of the nut is returned so that the axis of threaded hole becomes substantially aligned with the axis of the bolt, and then the nut is turned so as to insert part of a tapered portion into the insertion hole.
