...Lin Gu; Lei Li; Wansheng Zhao; Kamlakar P. Rjaurkar This paper reports on the efficiency and economy of bundled electrode in die-sinking electrical discharge machining (EDM). Bundled electrode was fabricated by putting several thin tubular or cylindrical cell electrodes together and forming...

... and the fabricated hole, which allows fabrication of holes with higher aspect ratios compared to those formed by a conventional EDM system using naked pipe electrodes. In this new system, the tip of the wire electrode is stripped by displacing the jacket, which produces continuous sparks for workpiece erosion...

...R. Ryan Vallance; Eric R. Marsh; Philip T. Smith Capacitive displacement sensors are widely used in precision manufacturing and metrology because they measure displacements with nanometer resolution. Prior literature usually treats capacitive sensors consisting of electrodes arranged as parallel...

...Wei Li Electrode wear is inherent in the resistance spot welding process. It determines the electrical and mechanical contact condition and thus strongly affects the resistance spot weld quality. A practical approach to minimizing the electrode wear effect is to compensate the welding current...

...D. F. Farson,; J. Z. Chen,; K. Ely and; T. Frech A high-speed video imaging system was employed to directly measure the electrode displacement of the small scale resistance spot welding (SSRSW) process. This measurement technique was chosen because it eliminates a number of potential error sources...

.... From the analysis, it is found that abnormal process conditions, such as axial misalignment, angular misalignment, poor fitup, edge weld, and electrode wear, significantly affect weld size and thus cause large variation in the weld quality. Although they may help increase the weld size in some cases...
