粗糙表面

This paper presented the research and exploration of mechanism and technics as well as the design of the magnetic circuit of this new compound machining, based on above, establishing the parameter model, meantime, analyzing influential effects on productivity of magnetic and EDM compound machining the holes through large numbers of experiments, including velcoity contrast experiments of pre-compound and after-compound machining with the change of current, velcoity contrast experiments of pre-compound and after-compound machining with the change of magnetic induction, velcoity contrast experiments of pre-compound and after-compound machining with the change of impulse width, experiments of the superficial roughness, experiments of the Electrode wastage, and intersectant experiments analysis as well as the change experiments of current waveforms. Through a number of experiments we analysed the influential effects of magnetic and EDM compound machining, compared the factors with EDM by oneself. A large of experiment records and deducibility have demonstrated that the productivity of magnetic and EDM compound machining is developed by 20%～400% than traditional EDM.
