A method for removing a fastener having a longitudinal shank from a workpiece using electro-discharge machining, EDM, the method comprising:
- contacting a portion of the fastener or workpiece with an EDM fixture, thereby:
- locating the EDM fixture and an EDM electrode relative to the fastener in a lateral direction;
- and
- establishing an electrical ground connection to the fastener via the EDM fixture;
- and
- eroding the fastener using the EDM electrode.
An electro-discharge machining, EDM, tool for removing fasteners having a longitudinal shank from a workpiece, the EDM tool comprising:
- an EDM electrode for eroding the fastener;
- an EDM fixture configured to locate the EDM tool and the EDM electrode relative to the fastener in a lateral direction and to establish an electrical ground connection with the fastener.
An EDM fixture comprising a recess for receiving a portion of a fastener,
- wherein the recess is configured to locate the EDM fixture and an EDM electrode of an EDM tool relative to the fastener in a lateral direction and to establish an electrical ground connection with the fastener.
