System and method for forming a nozzle inlet of a nozzle

A method for forming a nozzle inlet of a nozzle, the method comprising:

• providing a nozzle body including an external surface, the nozzle body forming a manifold passage;
• forming a nozzle aperture extending through the nozzle body between and to a nozzle inlet and a nozzle outlet, the nozzle inlet disposed at the manifold passage, the nozzle outlet disposed at the external surface, forming the nozzle aperture including forming an edge of the nozzle body at the nozzle inlet;
• positioning a machining tool of an electro-chemical machining (ECM) assembly in contact with the nozzle body at the nozzle inlet by attaching the machining tool to a flexible line and pulling the flexible line through the nozzle aperture to position the machining tool at the nozzle inlet;
• and
• with the machining tool positioned in contact with the nozzle body at the nozzle inlet, forming the nozzle inlet by removing the edge with the machining tool and forming a fillet of the nozzle body at the nozzle inlet, the fillet extending circumferentially about the nozzle inlet.
