摘要： A wirecut electrical discharge machining apparatus having silicon particles suspended in a dielectric solution that fills the machining gap. The silicon particles may be suspended in the dielectric solution prior to a machining operation or they may be mixed with the dielectric solution directly in the machining gap. Also, a silicon-coated electrode may be utilized. The silicon overcomes many of the limitations associated with conventional dielectric solutions, by allowing more uniformity of conductivity.

The control circuit contains: the control circuit contains an oscillator, reduction stages for the generation of elements which belong to the impulse signal, a counter for the addressing of impulse signal, a memory of a feedback circuit which detects the electrical conditions in the working gap, and a ROM with programmed memory locations, which are addressed by the counter according to the addresses of the impulse elements and by memory according to the addresses of the electrical conditions in the working gap, whereby the contents of the memory locations generate an output signal or no output signal. The principal circuit contains two electronic switches for the generation of a working impulse in the working gap when an output signal is present, and a control circuit which inhibits only one of two electronic counters.
