Material of electrodes for electrical discharge machining
Bednář, Šimon ; Chladil, Josef (oponent) ; Osička, Karel (vedoucí práce)
The diploma thesis deals with problematics of the graphite tool electrode material selection for electrical discharge machining. The thesis is divided into three parts. Theoretical analysis of unconventional technology of EDM based on available sources is summarized at the beggining. A price comparison of graphite materials from present suppliers distributed graphite materials in the Czech republic and Slovakia can be found in the second part. Four different quality grades of graphite and one copper material from a current supplier in GAMARTIS TRADE s.r.o. tool shop are put thru an experiment to find out how much the quality of electrode material influences factors such as the cavity accuracy, wear of a tool electrode, machining time, surface roughness etc.
