PROCESS USED TO SHAPE ITEMS OF EQUIPMENT COMPRISING A BLADE

A process for shaping a part (12) of the turbine vane type, includes providing a part (12) comprising a blade (14) in an initial shape, providing a nominal definition representing the part in a nominal shape, comparing the initial shape with the nominal definition to determine compliance or non-compliance, for a non-compliant datum, determining a force to be applied to the part to deform said part, applying a force to obtain the part in a deformed shape, comparing the deformed shape with the nominal definition to determine compliance or non-compliance, and training a self-learning algorithm (82).

Method for manufacturing components for gas turbine engines
10214794 · 2019-02-26 · ·

A method of manufacturing a component for a gas turbine engine. The method may include the steps of: providing a forged preform of the component that is made from a stainless steel alloy; identifying two non-overlapping portions of the component that together form a whole of the component: a target portion and a remainder portion; and treating the component with a regionally selective tempering process in which a treated region receives a tempering process while an untreated region is excluded from receiving the tempering process. The target portion may be the treated region while the remainder portion is the untreated region. The tempering process of the regionally selective tempering process may be configured to appreciably increase a hardness of the target portion of the component relative to a hardness of the remainder portion of the component.
