Abstract

A method for on-line removal of cathode depositions during electrochemical process. The process control unit ( ) is arranged to alternate the unipolar machining voltage pulses U with the voltage pulses of opposite polarity U to the work piece ( ) and the cathode ( ). The process control unit comprises an arrangement to determine the amount of cathode depositions on-line based on the operational parameter. Only in case the operational parameter exceeds the allowable level, the process control unit ( ) alternates the unipolar machining voltage pulses U with the voltage pulses of opposite polarity U In this case the cathode wear is minimized.
