ATAP 2330 - EDM RAM-G & M Programming & Machining

Credit Hours: 2.00


Prerequisites: None

This course teaches the general concepts of RAM Electrical Discharge Machining, a method involving electrical discharges between an electrode 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 EDM technology, followed by electrode material selection, proper design of electrodes, spark gap theory, and the principles of 2D and 3D electrode orbiting. Terminology used in the field of RAM, Wire, and Fast Hole EDM will be emphasized, accompanied by demonstrations, student programming, and EDM setup and operation.

Billable Contact Hours: 2
