Abstract: A device and method for surfacing a workpiece establishes a controlled electrostatic potential between an electrode and a workpiece then establishes a spark arc to melt a portion of the electrodes. The electrode is moved prior to any significant current heating of the workpiece and to extinguish the spark arc. The electrode is then moved into contact with the workpiece prior to solidifying of the electrode to deposit some of the electrode onto the workpiece.

Abstract: A machine used differently for various machining functions utilizing either the electronic spark erosion of metals, or electronic spark emission surface treatment of metallic material. The machine includes a novel means for monitoring and controlling the electrode position, with relation to the work piece. The machine is constructed to readily allow: various electrical component use changes; mechanical changes in axis and angularity of work head for optimum electrode positioning; electrical polarity changes together with vibratory mechanical electrode activation resulting in significant spark working activity. An electrical circuit provides resistance-capacitance for spark power generation incorporating reserve capacitance power pulsing for extra sparking capability. A machine: composed of easily maintainable modular segments allowing interchangeability by incorporation or deletion of sections. A machine providing portable adaptability for various types of work to be used completely or in sections.
