METHOD FOR ELECTROCHEMICAL MACHINING |
摘要 |
The present invention relates to electrochemical machining (ECM) of conductive materials and can be used for manufacturing stamps, mould tools and other workpieces of complex shape at the finishing stage of the machining process. Method for electrochemical machining with an oscillating machining electrode comprises the step of applying rectangular microsecond current pulses synchronized with the moment when a machining electrode and workpiece electrode are moved to a minimum distance towards each other. During the machining process, the amplitude of current pulses is increased and the pulse duration is adjusted in such a manner that the trailing edge of each pulse corresponds to the moment of maximum electrical conductivity of the interelectrode gap, the amplitude being increased until a predetermined roughness of the surface to be machined is achieved. The present invention is aimed at optimizing the finishing stage of the electrochemical machining process by achieving a predetermined surface roughness with a minimum current intensity.
