Its principle is to use the eroding effect on metals of successive electric spark discharges created by the breakdown of a dielectric liquid. Many researchers indicate a ratio of open circuit pulses from 10% to 35% during the EDM process.Therefor, reducing the frequency of these unproductive pulses could increase significantly the machining performance. A prognosis of open circuit pulses being impossible to do, a solution is proposed to transform an open circuit pulse into a productive one. The basic idea of this solution is to increase the probability to obtain a breakdown of the dielectric liquid. The proposed technique consists in dividing the voltage pulse in a large number of elementary pulses, realising by that an enhancement of the thermal phenomena in the dielectric liquid, favouring the breakdown. To apply this solution, the architecture of a pulse generator, able to detect in real time an open circuit pulse and to apply in succession a divided pulse was conceived. This book is of interest for all engineers involved in improving the EDM techique.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783330867574\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783330867574","offer_id":39427492249693,"sku":"9783330867574","price":28.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/cff4a735-0b67-4e73-938f-fb4bd1b6ca10.jpg?v=1770269234","url":"https:\/\/shop.autorenwelt.de\/en\/products\/using-divided-pulses-to-avoid-open-circuits-in-edm-von-constantin-diaconescu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
