Design of Energy-Controllable Pulse Generator on Micro WEDM
Generator is one of the key factors in Micro WEDM, which can affect machining quality, precision and efficiency largely. The factors influencing discharge energy are discussed and analyzed, the pulse addition method increasing energy density under maintaining the single pulse energy is advanced. To reduce the influence of voltage to single pulse energy, the gap voltage is also controlled. The generator is designed and the validating experiment shows this generator can increase machining efficiency and quality to a certain extent.
