Development of a TriaxialMicro EDM Machine Tool Based on Programmable Multi-Axes Controller (PMAC)
Abstract:
Based on the research of key technologies for achieving micro EDM process, a triaxialmicro EDM machine tool based on PMAC has been developed. The micro EDM machining tool consists of four parts: triaxial precision motion platform, motion control system, micro-energy pulse generator and CCD microscope imaging system. The hardware and software control system based on industrial control computer and PMAC has been researched. The motion control program and PLC program have been developed for precise controlling the triaxial precision motion platform. The indispensable functions for micro EDM process such as contact perception function for measurement; fast servo control strategy for short circuit and so on has been achieved. Through a number of processing tests, it is proved that the triaxial micro EDM machine tool has the ability for machining micro holes, micro slots and micro structures steadily.
