A two-step electrodischarge machining method was proposed for fabricating microgrooves with varied cross-sections on hard materials. Firstly, tungsten tool electrodes were shaped by wire electrodischarge grinding, and then the resulting tool electrodes were used to electrodischarge machine microgrooves on stainless steel. Preliminary experimental results showed that, in the first step, a sharp ...

This paper describes a new inprocess electrodischarge dressing method for metal bonded diamond wheels. In order to simplify a process of inprocess electrodischarge dressing, we propose to utilize a floating nozzle method, one of effective coolant supply methods, since an appropriate gap for ED dressing is formed between the grinding wheel and the tip of the floating nozzle by the coolant.
