<p>A method for on-line removal of cathode depositions during electrochemical process. The process control means (30) are arranged to alternate the unipolar machining voltage pulses U1 with the voltage pulses of opposite polarity U2 to the work piece (2) and the cathode (3). The process control means comprise 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 means (30) alternate the unipolar machining voltage pulses U1 with the voltage pulses of opposite polarity U2. In this case the cathode wear is minimized.</p> |
