ATAP 2340 - EDM WIRE-G & M Programming & Machining

Credit Hours: 2.00

Prerequisites: None

This course teaches the general concepts of Wire Electrical Discharge Machining, a method involving electrical discharges between a wire and a conductive workpiece to remove material in a non-conventional manner. Through lecture and lab assignments, the student will learn multiple EDM skills, beginning with an overview of Wire EDM technology, followed by wire selection, spark gap theory, and the principles of rough cuts and skim passes. Terminology used in the field of Wire EDM will be emphasized, accompanied by demonstrations, student programming, and EDM setup and operation.

Billable Contact Hours: 2
