Electrical Discharge Machining Industry Information

Electrical Discharge Machining

Electrical discharge machining is a tooling method that uses electrical energy to cut, drill, etch, and machine metal parts and is one of the most accurate types of machining. Hard metals and other materials are difficult to machine cleanly with conventional mechanical-cutting methods; therefore, EDM machining is used.

Applications of Electrical Discharge Machining

Applications, such as manufacturing molds and dies for die casting and forging are common uses of conventional EDM. It is also used for parts and components in many industries, such as food and beverage, automobile, defense, electronics, and medical. Using a dielectric fluid bath to prevent unwanted sparks and to flush away machining debris, EDM cutting and drilling is able to produce parts with high tolerances and accuracy. As there is no contact between the machine and the work piece, there is no potential for impact damage either, resulting in a high quality piece with minimal imperfections and wastage. EDM is typically used for electrically conductive materials and those commonly processed with CNC EDM include aluminum, copper, zinc, bronze, tin, silicon, titanium, and stainless steel.

How Electrical Discharge Machining Works

The process erodes the material in the path of the EDM tool using electrical discharges or sparks. The "tool electrode" forms an arc to the "work piece electrode" as the two are brought closer together, creating the intense electric field which is responsible for removing material.

The actual electrical discharge machining is accomplished through carefully created sparks, which are electrical discharges that can generate heat anywhere from eight to twenty thousand degrees. A shaped tool, electrode, or wire is used to generate the series of sparks, depending on the process. There is no actual physical cutting contact, but rather a conductive path that is established between the electrode and the material, which melts away the unwanted portions of the work piece.

Benefits of Using Electrical Discharge Machining

Electrical discharge machining has advantages over other machining techniques due to its ability to create complex and intricate parts with a high degree of accuracy. Another advantage of electrical discharge machining is its ability to machine parts on an extremely small scale.

Notable Types of Electrical Discharge Machining

Different types of machining include sinker EDM (which is used for more complex geometries and for holes and patterns) and wire EDM (which specifically cuts patterns and shapes through a selected part or assembly). CNC machines are used to guide, monitor, and control the electrical discharge machining process, as well as CAD and CAM software.

Production Wire EDM Techniques That Are Efficient & Cost Effective

Written By, Andy Dziennik Senior Project Manager Xact Wire EDM Corp. Waukesha, WI  Wire EDM, once considered a non-traditional machining method, has been around for many years now and is utilized extensively in many industries. It is a unique process that is used to produce parts for numerous applications with remarkably high precision from most conductive materials. In today’s world, tolerances keep getting tighter and tighter. For this reason, EDM is being used more often as it is one of the best methods for machining accurate parts. The wire electrical...
