A Method and machine tool for compensating a wear of an electrode that machines a workpiece. The method includes selecting a current pocket from plural pockets of the workpiece; updating a wear compensation to be applied to the electrode for the current pocket based on wear compensation of a previous pocket, where the previous pocket is adjacent to the current pocket; and applying the updated wear compensation to the electrode for machining the current pocket.

Method for compensating a wear of an electrode

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.
