Abstract
A method of forming a curved-shaped processing hole in a workpiece by electromechanical machining includes a step of feeding an electrolytic solution through an inner channel of a processing electrode and jetting the electrolytic solution from an outlet opening of the inner channel disposed on a tip surface of the processing electrode, a step of applying a potential difference between the processing electrode and the workpiece while jetting the electrolytic solution from the outlet opening of the processing electrode, and a step of forming the curved-shaped processing hole in the workpiece. In the jetting step, at least one of a current density distribution on the tip surface of the processing electrode or a flow velocity distribution of the electrolytic solution jetted from the outlet opening is eccentric to a downstream side of a curving direction of the processing hole with respect to an axial center of the tip surface.
