First claim
Opening claim text (preview).
We claim: 1. An electrical discharge machining electrode assembly, comprising: an electrode base; and an electrode coating containing diamond that is electroplated to the electrode base, wherein the electrode coating has a [111] crystal graphic direction. 2. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode coating comprises a chemical vapor deposition diamond material. 3. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode coating comprises a polycrystalline diamond material. 4. The electrical discharge machining electrode assembly of claim 3 , wherein the polycrystalline diamond material is sintered with boron. 5. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode assembly is a non-consumable electrode assembly. 6. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode assembly is a copperless electrode assembly. 7. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode assembly is a graphiteless electrode assembly. 8. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode assembly is a reusable electrode assembly. 9. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode has a contour mimicking a contour of a turbomachine component of a gas turbine engine. 10. An electrical discharge machining assembly, comprising: an electrode having a portion that is electroplated with a coating containing diamond; and a power supply configured to power the electrode, wherein current selectively moves from the electrode to a component to remove material from the component when the electrode is powered, wherein the electrode coating has a [111] crystal graphic direction. 11. The electrical discharge machining assembly of claim 10 , wherein the coating containing diamond comprises a chemical vapor deposition diamond. 12. The electrical discharge machining assembly of claim 10 , wherein the coating containing diamond comprises a polycrystalline diamond. 13. The electrical discharge machining electrode assembly of claim 1 , wherein the electrode base is separate and distinct from the electrode coating. 14. An electrical discharge machining electrode assembly, comprising: an electrode base having a first material composition; and an electrode coating having a second material composition that includes diamond, the electrode coating electroplated to the electrode base, the electrode coating providing a layer that is separate and distinct from the electrode base, wherein the electrode coating has a [111] crystal graphic direction.
