Introduction to Electric Discharge Machining

2. Course Prefix & Number:
MTTS 2116

3. Course Credits and Contact Hours:

Credits: 2

Lab Hours: 4

4. Course Description:

Students will be introduced to the complex operations of electric discharge machining (EDM). Students will experience both wire and sink EDM operations and applications of these technologies for efficient production of highly technical processes. Electrical discharge machining, sometimes colloquially also referred to as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks).
