RESEARCH ON LAMINATED REMOVAL MICRO-EDM

A laminated removal micro electrical discharge machining(LR-MEDM) method is proposed by combine the concept of laminated machining in rapid prototype machining and of the electrode uniform wear in EDM. The basic principle and carry out way of LR-MEMD are studied and analyzed systemically. Especially to its key problems, such as the electrode wear and its compensate policy, the electrode movement planning in LR-MEDM. As an example, a simplified mold of IC socket with 40 pins and a 3D surface are machined by LR-MEDM. Experiments show that LR-MEDM can expectably achieve better machining accuracy with much lower expense on almost any conductive materials, and it shows great potential of application in the future.
