Abstract: During the micro-electrical discharge machining (micro-EDM) process, the dielectric property of narrow interelectrode gap is transiently changing. With the hysteretic servomotion of spindle, the effective discharge ratio ...

Abstract: In micro-electrical discharge machining (EDM), it is difficult to guarantee machining efficiency and accuracy when further increasing the aspect ratio of microholes due to poor circulation of working fluid and removal of ...

Abstract: Stray current causes undesired material dissolution in micro-electrochemical machining (micro-ECM). The reduction of stray corrosion, caused by stray current, continues to be a major challenge for accuracy improvement. To ...

Abstract: Microstructures determine flow properties of microfluidic chip. Micromold forming is an effective method to realize mass manufacturing of microfluidic chips. This requires to machine some kind of special microstructure of ...

Abstract: Natural fractures may not be developed in hot dry rock reservoirs, and tectonism or fracturing can induce the shear deformation of fractures and result in large-scale rough-walled fractures. Previous studies usually ignore ...
