ABSTRACT:
A traveling wire electrical machining system makes use of a single-strand traveling wire which is guided in a plurality of passes across a workpiece to cut through the latter at a plurality of parallel locations. According to the invention, the machining power supply has a plurality of outputs each of which is connected to a respective stretch of the traveling wire, thereby equalizing the machining current for each of the multiple stretches.
