CHOOSING BETWEEN DIFFERENT EDM MACHINES

Abstract

Electrical discharge machining is one of the most studied nonconventional technologies. Research in the field is extremely numerous and the use of electrical erosion machines is very widespread. Most often, when purchasing an electrical erosion machine, only the machine's price and the productivity are considered. The paper shows that there are many more factors that should be taken into account, and therefore sometimes it is necessary to perform a multi-criteria analyse to decide on the “perfect” machine. The criteria are chosen by each user, depending on the momentary and perspective needs.
