Abstract:

The following study examines the experimental determination of the electrochemical machinability of cemented carbides with a neutral electrolyte solution. In previous research, a removal mechanism of tungsten carbide-cobalt was demonstrated applying pulsed electrochemical machining. This work focuses on the material removal of tungsten carbide-cobalt with the further developed modulated pulsed electrochemical machining process according to DIN SPEC 91399. Compared to the preceding investigation, the modulated pulsed technique demonstrates a similar removal mechanism with higher current efficiencies.
