A cooling aperture is formed in the preform component. The cooling aperture includes a diffuser section and a meter section. The diffuser section extends through the outer coating and into the substrate. The meter section extends within the substrate. The forming of the cooling aperture includes: forming the diffuser section using a first machining process; and forming the meter section using a second machining process that is different than the first machining process.

A manufacturing method is provided. During this method, a preform component is provided for a turbine engine. The preform component includes a substrate comprising electrically conductive material having an outer coating comprising non-electrically conductive material applied over a surface of the substrate. A preform aperture is formed in the preform component using an electrical discharge machining electrode. The preform aperture includes a meter section of a cooling aperture in the substrate. The preform aperture also includes a pilot hole in the outer coating. A diffuser section of the cooling aperture is formed in at least the outer coating using a second machining process.

The disclosure identifies an apparatus, system of and method for using an interchangeable fluid jet tool, the tool in at least one embodiment being a waterjet tool device that may be interchangeably integrated with a machine having any form of reciprocating or rotating pump (which may be used as a coolant or cutting fluid pump), and coupled with a motor powered rotatory drive machine, such as a spindle, having any type of tool interchange attachment and tool holders (some industry examples being CAT Taper, HSK, BT, R8, Jacobs, or other type, including specific configurations to attach to heavy mobile construction or demolition equipment for the purposes of mining, cutting stone blocks, slabs, and other shapes, or boring tunnels or passages, in stone or other hard compacted material).

Systems and methods are provided for viscous and/or chemically erosive flow machining of work pieces. In certain examples, a tool for flow machining may be disclosed. The tool may include a cavity configured to receive a work piece and one or more inlets and outlets for viscous media flow. Viscous media and/or chemically erosive media can be flowed into the cavity and, via a media flow path, can be used to machine the work piece.

An abrasive waterjet system in accordance with an embodiment of the present technology includes a cutting head, a catcher downstream from the cutting head, and a conveyance configured to carry slurry including abrasive material and liquid collected from the catcher toward the cutting head. The cutting head includes a jet-forming orifice and a mixing chamber downstream from the jet-forming orifice. The cutting head also includes a slurry inlet through which the mixing chamber receives slurry including abrasive material and liquid collected from the catcher. The abrasive waterjet system can be configured for substantially closed-loop recycling of wet abrasive material. This can be useful, for example, to increase abrasive material utilization efficiency and to decrease abrasive material disposal costs. These and/or other benefits may be realized both in the context of low pressure abrasive waterjet systems and in the context of high pressure abrasive waterjet systems.

A lance, in particular for jointly dispensing a pressurized fluid and an additive for penetrating walls, includes a lance body, a handle arrangement, multiple channels and actuator arrangements interacting therewith, a nozzle arrangement as well as at least one container for the additive. The actuator arrangements selectively control the fluid being conducted in the first channel, the additive being conducted in the second channel, and the ambient air being conducted in the third channel to a first nozzle body. The third channel forms a line connection between the ambient air and a mixing chamber of the first nozzle body. The second actuator arrangement with its second actuator directly acts on the third channel and indirectly controls the admixing of the additive via the second channel into the mixing chamber.

Methods and masks for manufacturing component of gas turbine engines are described. The methods include applying a mask to a protected surface of the component, the component having a designated surface to be treated by a shot peen operation. The mask includes a full masking portion configured to prevent a shot peen media from impacting the protected surface. A masking control region is arranged around the designated surface. The masking control region is configured to control an amount of force imparted to the component by shot peen media during the shot peen operation, wherein the masking control region extends from the full masking portion to the designated surface. The designated surface is shot peened with shot peen media to form a compressive stress region within the component proximate the designated surface and a tapering transition of compressive forces within the component proximate the masking control region.

A method for creating a three-dimensional (3D) mark in a protective coating including at least one of a TBC and a bond coating over a metal part, is provided. The method may include positioning a mask over the protective coating, the mask including an opening pattern therein; and performing an abrasive waterjet process on the protective coating using the mask. The abrasive waterjet erodes a first portion of the protective coating exposed through the first opening pattern to create the 3D mark. The mask is removed, leaving the 3D mark in the protective coating. The 3D mark only partially penetrates through the protective coating. A metal part may include a metal body, a protective coating over the metal body, and the 3D mark in the protective coating, is also provided. The 3D mark in the protective coating may include an opening having a width of between 30 and 300 micrometers.
