The present disclosure relates to the technical field of aerospace, and provides a machining method for an ultra-high strength steel high-aspect-ratio wind tunnel test model part. The machining method includes the following steps: a) selecting a material; b) performing preliminary treatment, such as forging and solid solution heat treatment, on the material; c) performing rough milling to obtain a wing main body profile, process reference blocks, and grooves and holes with large sizes on a molded surface; d) performing finish milling on all machining features of a wing main body; e) removing all process reference blocks except the first process reference block; f) performing aging strengthening treatment when the wing main body is lifted; h) removing a process reference block at a wing main body root; and h) performing shaping treatment on the wing main body.

A process of repairing a component includes identifying a void in a component; determining at least one approximate physical configuration of the void; inserting borescope into the component in order to view the void; providing a repair rod approximately equivalent to at least one of the least one approximate physical configuration of the void; inserting the repair rod into component; confirming insertion of the repair rod in the void; separating the repair rod to leave a repair plug in the void; and depositing braze paste over the repair plug in the void.

A method for investigating an electrolyte solution for processing a component, particularly a component or a component material of an aircraft engine, by near infrared spectroscopy.

A method of manufacturing an additively manufactured object includes: checking, for an additively manufactured object including a plurality of internal passages, the presence or absence of a deposit in each inner wall surface of the plurality of internal passages; and selectively removing the deposit from the internal passage in which the deposit has been detected in the checking, among the plurality of internal passages.

The invention relates to a machining apparatus for electrochemically removing component layers of a component, having at least one electrode, which is mounted so as to be movable along at least one infeed axis, and having at least one auxiliary electrode, which is mounted so as to be movable along an auxiliary infeed axis, wherein a gap for arranging the component for electrochemically removing the component layers extends between the at least one electrode and the at least one auxiliary electrode. At least the infeed axis and a longitudinal extension direction of the gap enclose an acute angle with each other. The machining apparatus comprises at least one oscillation device (40), which is set up at least to move the at least one electrode in an oscillating manner along the infeed axis and relative to the at least one auxiliary electrode.

The present method for machining a part includes wire electro-discharge machining the part to create a recast layer, and then removing a zinc content of the recast layer without substantially altering the remainder of the initial composition make-up of the recast layer. The final composition make-up of the recast layer is substantially identical to the initial composition make-up except for the removed zinc content.

The invention relates to an ECM system comprising a holder for the arranging of at least one component to be machined and at least one machining station for the electrochemical machining of the at least one component at at least one machining position. The ECM system has a positioning apparatus, which is designed to mount, in a predefined position, a machining platform arranged on the positioning apparatus, and the machining platform comprises at least one machining station having at least one electrode arranged thereon, which electrode can be moved along a machining path in order to machine the at least one component that can be arranged on the holder.

An EDM machine includes a machine head, a wire guide, a machining wire extending from the wire guide to the machine head, a rotary table mounted to a first surface and a fixed table mounted to the rotary table, and a fixture mounted to the fixed table. The fixture includes a mounting portion substantially circumscribing the fixture. The mounting portion further includes a mounting surface. The mounting surface is closer to a first surface than an upper surface of the fixed table.
