Ram EDM Industry Information

Ram EDM

Ram EDM, or electrical discharge machining, goes by many names, including conventional EDM, sinker EDM, and cavity type EDM. It produces parts through eroding material in the path of an electrical field using electrical discharges (or sparks) that can generate heat anywhere from eight to twenty thousand degrees. Ram EDM is used for more complex geometries where electrodes are used to erode the desired shape into the part or assembly.

Applications of Ram EDM

Industries that commonly use electrical discharge machining include aerospace, medical, tool and die, automobile, and military. Ram EDM is ideal for such applications as injection mold tooling, micro hole drilling, keyways, washers, and scientific research apparatus, as these applications often require high tolerances and precision components.

Process of Ram EDM

For extremely high precision requirements, CNC EDM machines are used to guide, monitor, and control the electrical discharge machining process, as well as CAD and CAM software to ensure accuracy. Ram type EDM differs from its counterpart, wire EDM, in terms of the type of electrode used. Consisting of an electrode and a workpiece (the material being processed), the electrode is used to generate a series of sparks and is connected to the workpiece through a power supply. There is no actual contact between the electrode and the workpiece, but rather a conductive path that is established between the electrode and the material. Ram EDM can be applied to hard materials, including stainless steel, copper, graphite, and exotic metals that would cause difficulties during conventional machining.

Advantages and Disadvantages of Using Ram EDM

Ram EDM is advantageous due to its ability to create complex and intricate parts with a high degree of accuracy. This process takes place in a bath of dielectric fluid, which prevents premature sparking and flushes away debris, conducts electricity between the electrode and the work piece, and then flushes out the melted material. Therefore, while using this process, the workpiece is not deformed from any impact, as there is no direct contact between the electrode and the material, and the workpiece is burr-free after completion and saved from heat damage because very little material-damaging heat is generated during the procedure. Ram EDM has an advantage over wire EDM as well, because ram EDM does not cut all the way through the material, thus producing parts that wire EDM cannot. However, a disadvantage to ram EDM is the additional time and cost necessary to create electrodes. Common plunge EDM electrodes include machined graphite, copper tungsten, and brass.
