Abstract

A spark erosion machine which includes a pulsed power supply PS1 for creating sparks between a working electrode 12 and a workpiece 14, wherein means PS2 are provided for applying across the spark gap a monitoring voltage from a constant d.c. high impedance source, said monitoring voltage being greater than the voltage of each pulse from the pulsed supply PS1, and wherein the voltage V across the spark gap is used to control the spacing between electrode 12 and workpiece 14 and/or to control the mark-to-space ratio of the pulses 11 from the pulsed power supply PS1. <IMAGE>
