EDM 26 MoldMaking Technology —— MAY 2017 By Robert Fothergill Image courtesy of Poco Graphite. Contact your electrode material supplier to attend a training session on how electrode performance can impact EDM efficiency. S inker EDM technology has improved significantly over the years, changing many of the processes and decisions that an EDM operator will face when operating the machine. Even though operators may have access to the latest in machine tool technology, it is still important for them to receive adequate training to understand machine parameters and the impact each one has on the finished product. Most EDM training is separated into basic and advanced levels of operation, and covers topics such as EDM theory, preventive maintenance, operational practices, programming and advanced technologies. However, these are primarily focused on the sinker EDM itself and not on the consumable materials associated with this machine. For example, the dielectric oil used in the EDM process, the filters used to keep the dielectric fluid clean and even the electrode material used to complete the burn. Understanding electrode material selection and the relationship among the electrode, workpiece material and machine parameters can improve EDM efficiency. AN ADDED LAYER OF EDM KNOWLEDGE Did you know that the electrode material used in the EDM process has a direct correlation to the performance and effi- ciency of the EDM burn? This is similar to the food we eat to maintain good health and remain at the best physical condi- tion possible. If we eat healthy and exercise, then we can expect to have energy and fewer illnesses than if we were to consume mostly junk food and live an inactive life. In this same regard, the electrode material used in the EDM burn must be matched to the application to guarantee success at the highest level of productivity. Sure, even the
