ABSTRACT:
A servo feed system for EDM in which feed of the electrode is controlled responsive to a gap voltage signal with appropriate feedback changes to control servo velocity and upfeed and downfeed gain as the gap voltage level changes. A further feature involves the imposition of a dither circuit between the gap voltage signal amplifier and the servo valve coil in such manner as to continuously apply dither in a manner independent of changes in gap voltage.
