Abstract
A processing method of a semi-processed product for obtaining a rotor equipped with a series of blades integral therewith by using a rotating tool such as a cutter, integral or with inserts. The processing method includes a) forming a hole into the semi-processed product; b) forming a series of cavities in the semi-processed product by removing material with the rotating tool to create the series of blades, starting from the hole and following predetermined paths; and c) removing material from the semi-processed product by advancing the rotating tool along its rotation axis and not removing material when the rotating tool advances along the predetermined paths. The rotation axis of the rotating tool is misaligned with respect to an axis of the hole.
