Abstract
The invention relates to a method of fabricating a part including at least one face in the form of a surface of revolution from a structure made up of a plurality of thin-walled hollow bodies. In order to ensure that cutting takes place without damaging the walls and/or the bonds between the walls of the hollow bodies, the part is machined in the structure by means of a water jet. More precisely, during machining, the structure is attacked with a jet of water under pressure that is directed tangentially relative to the outer envelope of said at least one face to be made in the form of a surface of revolution.
