Abstract
For an electromechanical machining of a work piece there is an optimal pulse duration for the machining pulses corresponding to the maximum copying accuracy. Such an optimal pulse duration corresponds to a certain value of the gap. By alternating the machining pulses with measurement pulses it is possible to obtain an accurate information about the gap dimensions on-line during the electrochemical machining process. The process control means ( ) are used to automate the electromechanical machining, while keeping it in the optimal mode. For this purpose the process control means ( ) comprise the pulse control unit ( ) to establish the pulse duration of the voltage pulses to be applied across the gap ( ).
