ABSTRACT:
An EDM parameter control system comprising a microprocessor having a memory for storing therein a programmed set of microinstructions representing selectable values for each of the EDM parameters. A gap monitoring circuit derives from the EDM gap a gap status signal representing characteristics thereof, the gap status signal being applied through an input interface to the microprocessor wherein it is used to microprocess the previously stored parameter data to provide control signals applicable to respective control devices for regulating the machining parameters (e.g. machining pulse on-time and off-time, gap spacing, tool reciprocation commands, dielectric supply control parameters). Preferably, the parameters are weighted in microprocessing and the output interface is constituted by a time-sharing unit for actuating the control devices in preset time divisions.
