摘要：

It is shown and confirmed that the behaviour of a pulsed electromagnetic field influences the surface roughness especially in superfinishing electrodischarge machining (EDM). In accordance with technological experiments, instrumental measuring and theoretical analysis, some principles of the microenergy EDM process are discovered. An effective method concerning the generator and conducts is proposed to ensure that all discharges occur with desired pulse parameters. A best surface roughness of 0.04 μm Ra is achieved. © 1990.
