EDM is commonly used for machining of electrically conductive hard metals and alloys Only sparking is desired in EDM rather than arcing. • 7. Milling is a process performed with a machine in which the cutters rotate to remove the material from the work piece present in the direction of the angle with the tool axis. Several experiments are conducted to study the effect of three process parameters: peak current (I p), pulse on-time (T on) and electrode material on the machining process of H13 die steel. Arcing leads to localised material removal at a particular point whereas sparks get distributed all over the tool surface leading to uniformly distributed material removal under the tool. You can change your ad preferences anytime. 2 Courtesy Makino In this work, different EDM process parameters are investigated on H13 die steel. EDM spark erosion is same as electric spark which burn a small hole in a piece of metal through witch it contacts. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes. Grinding - LinkedIn SlideShare.
