Structure of process energy sources for time-parallel combined processes

The structure of the process energy source in the case of combined techniques is determined by the main and assisting processes. At classical combinations of EDM and ECM the changed dynamic load conditions are shown, and the importance of the process-dependent rf noise for process identification is explained. The modular design may be used favorably for shaping the current and/or voltage pulses, especially for changing the rise and fall time of pulses. The structure adaption of the process energy sources to the hybrid time-parallel processes is an important task for process optimization and the effective utilization of the process combination for the provided case of application.
