    摘要： An electroerosive contouring wire-cutting apparatus using a distilled or deionized water machining medium of a specific resistivity controlled to be in a range between 10.sup.2 and 10.sup.5 ohm-cm, and having abrasive particles of TiC, TiN, B.sub.4 C, BN, SiC, Al.sub.2 O.sub.3 and/or SiO.sub.2 of for example a particle size in the order of microns for delivery by the medium to the machining gap. A high-frequency vibration of a frequency of 1 kHz to 1 MHz is imparted to the wire electrode traveling through the workpiece in a direction transverse to the wire axis to enhance the combined electroerosive and abrasive actions at the machining gap. The machining medium is delivered by a nozzle, retrieved at a collector, and separated into its liquid and solid components in a separator. After deionizing the liquid and extracting the machining products, the abrasive particles and deionized water are mixed and recirculated through the nozzle.

    摘要： METHODS OF ELECTROCHEMICAL MACHINING IN WHICH STRAY MACHINING IS INHIBITED AND A HIGH FEED RATE AND A CONSTANT WORKING GAP CAN BE ACHIEVED. STRAY MACHINING IS INHIBITED BY A PROTECTIVE ELECTRODE PROVIDED ON THE CATHODIC TOOL AND MAINTAINED AT A POSITIVE ELECTRICAL POTENTIAL RELATIVE TO THE TOOL TO CONFINE ELECTRICAL CURRENT FLOW BETWEEN THE TOOL AND AN ANODIC WORKPIECE TO REGIONS WHERE EROSION IS DESIRED. HIGH FEED RATES ARE ACHIEVED BY APPROPRIATE TAPERING OF A MACHINING, LAND ON THE TOOL. CONSTANT WORKING GRAPS ARE ACHIEVED BY NORMALIZING THE MACHINING VOLTAGE WITH THE AID OF VOLTAGE SENSING PROBES, BY CONTROLLING THE CONDUCTIVITY OF THE ELECTROLYTE OR BY FORMING STABLE GLOBULES OF ELECTPOLYTE IN A DIELECTRIC CARRIER LIQUID, THE GLOBULES HAVING A DIAMETER MATCHING THE DESIRED GAP.
