Micro-electric discharge milling machine with spark control

A micro-electric discharge machine, comprising:

• a base having an X-axis guide plate mounted thereon, the X-axis guide plate allowing for movement in the X-direction;
• a Y-axis guide plate mounted on the X-axis guide plate, the Y-axis guide plate allowing for movement in the Y-direction;
• a dielectric bin located on the Y-axis guide plate, the dielectric bin being movable in the X-direction and the Y-direction via the X-axis guide plate and Y-axis guide plate, respectively;
• a workpiece platform located within the dielectric bin, the workpiece platform being adapted for securing a workpiece;
• a vertical plate extending from the base, the vertical plate having a Z-axis guide plate;
• a drill chuck mounted on the Z-axis guide plate for securing a rotating electrode;
• a spark control circuit monitoring current to the workpiece and generating a spark between the rotating electrode and a surface of the workpiece thereby continuously shifting the location of the rotating electrode and delivering the spark onto a surface of the workpiece to evaporate and melt a portion of the surface of the workpiece;
• and
• a dielectric fluid inlet block mounted on the Z-axis guide plate for directing a dielectric fluid to a machining spot.
