Abstract
An electronic depth controller is associated with EDM apparatus for controlling the depth of holes which are machined in workpieces by the EDM apparatus. The electronic depth controller comprises its own microprocessor which acts upon selectable input data from a control panel to provide signals relating to hole depth control to the main control system of the EDM apparatus. The electronic depth controller is selectively operable to one or the other or both of two operating modes. Data relating to each mode is input to the system via switches on the control panel.
