Abstract

1. Способ механической обработки лопатки (10) в станке для объемной механической обработки, причем упомянутая лопатка (10) содержит аэродинамическое перо (18), полку (12), содержащую передний и задний держатели (12А, 12В), образованные соответственно под ее передним и задним участками для поддержки уплотнительного кожуха (20), замок (16) лопатки и стойку (14), расположенную между упомянутой полкой и упомянутым замком лопатки, причем упомянутый способ отличается тем, что упомянутые передний и задний держатели также образуют две опорные точки (22А, 22В) для шеститочечной системы позиционирования для позиционирования упомянутой лопатки в упомянутом станке для объемной механической обработки.2. Способ механической обработки по п. 1, отличающийся тем, что упомянутые опорные точки образованы на стороне спинки упомянутой стойки.3. Газовая турбина, включающая в себя множество лопаток, полученных способом механической обработки по п. 1 или 2.
