Abstract

See full text

A method is provided comprising identifying an alignment point of a workpiece; positioning a first end of an electrode in the direction of the alignment point of the workpiece; applying a first voltage to the electrode wherein the applied first voltage generates a spark; rotating the electrode in a first direction; advancing the electrode toward the alignment point by a first distance wherein advancing the electrode and applying the first voltage creates a first orifice section; applying a second voltage to the electrode and modifying one or more operational parameters of the electrode; advancing the electrode toward the alignment point by a second distance wherein advancing the electrode and applying the second voltage causes formation of at least a second orifice section; wherein the first and second orifice sections cooperate to form an orifice comprising a first flow area and a second flow area.
