ABSTRACT:
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.
