Abstract:
A tool for forming a trench and a plurality of cooling holes within the trench includes a body, the body including a ridge portion extending along a first side of the tool. The ridge portion is operable to mate with a workpiece to form a trench on the workpiece. A plurality of electrodes extend from the ridge portion and are oriented to form a plurality of cooling holes within the trench on the workpiece.
