Interesting new series by Practical Machinist - EDM Machining section the link was received in the Practical Machinist newsletter.

The first episode video starts with the basic concepts of wire electric discharge machining (WEDM) , and is explained and presented by Zero Tolerance LLC.

“There are many different names for this subtractive manufacturing process: spark machining, spark eroding, die sinking... the list goes on and electrical discharge machining is considered a "non traditional" or "non conventional" machining process. This video, Introduction to Electrical Discharge Machining, will show you how, what, and why”

The key sections of the video are as follow:

00:15 Introduction to Zero Tolerance and how they use electrical discharge machining to create their plastic injection molds. 2:14 Beginning the electrical discharge machining process of an intricate mold. 3:37 Using the electrode holder and how it works. 8:43 Continuing the electrical discharge machining process of an intricate mold. 11:24 Quick lesson about how the electrode and voltage create the spark and cut the metal. 13:31 No broken cutters with hardened steel and EDM.

Practical Machinist intends to publish more EDM videos which we will share on the GIP Blog as they appear.
