A manufacturing apparatus for manufacturing a blower blade including a plurality of blade portions having the same shape and arranged around a rotation axis line includes a machining device for machining the blower blade and a control device for controlling the machining device. The control device includes a command creation unit for creating an operation command to the machining device according to a machining program and a machining parameter, a balance measurement unit for measuring balance of the blower blade, and a machining amount adjustment unit configured to individually adjust a machining amount of each of the blade portions without changing the machining program, based on data of the balance of the blower blade measured by the balance measurement unit so as to reduce unbalance of the blower blade. A manufacturing method using the above-described manufacturing apparatus is also provided.

The invention relates to a method for producing multiple metal turbine engine parts, comprising steps consisting in: a) casting a metal alloy in a mold in order to produce a blank (3); and b) machining the blank in order to produce the parts,
characterized in that the blank obtained by casting is a solid polyhedron with two generally trapezoidal opposing sides (30a, 30b), and the parts are machined in the blank.

A method of machining cooling holes includes providing a workpiece in which a cooling hole is to be formed. The cooling hole, once formed, defines distinct first and second sections. The workpiece is secured in a fixture that is mounted in a first machine. In the first machine, a laser is used to drill a through-hole in a wall of the workpiece. The through-hole is spatially common to the first and second sections of the cooling hole. After drilling the through-hole, the fixture with the workpiece secured therein is removed from the first machine and mounted in a second machine. In the second machine, ultrasonic machining is used to expand a portion of the through-hole to form the second section. An abrasive slurry used in the process is drained through the through-hole during the ultrasonic machining.

A vibropeening apparatus comprises a main frame, an enclosure receivable within the main frame, a rotary drive mechanism, and an article to be vibropeened. The enclosure defines an internal volume, the internal volume accommodating a vibropeening bed. The article is positioned within the internal volume, and the rotary drive mechanism is to configured to impart a rotary motion to the enclosure within the main frame.

A method for producing a rotor vane (10) for a turbomachine, including producing a rough casting, the heel of which has a downstream lip (121) with a transverse increased thickness (130) such that the lip has an upstream surface (134) substantially parallel to an axis The method further includes machining said increased thickness so that the downstream lip has an upstream surface (138) inclined in relation to the axis.

A method for manufacturing a blade, the method includes casting a nickel alloy blade precursor having an airfoil and a root. The airfoil and the root are solution heat treating differently from each other. After the solution heat treating, the root is wrought processed. After the wrought processing, an exterior of the root is machined.

A method of post processing a laser peened component to remove a laser remelt layer is proposed. The post processing includes a series of steps including grit blasting, chemical etching and mechanical finishing the component. This will ensure that the mechanical property (i.e., damage tolerance) benefit of laser peening is restored to the surface of the component.
