STABILITY IN ELECTRICAL DISCHARGE MACHINING PROCESSES
This paper provides a general idea of what reliability of metal processing is, including when used for electrical discharge machining (EDM). We present and explain in detail all main causes of instability manifestations resulting from EDM, as well as the key ways to eliminate this instability effect. Further on in the paper the problem of EPM controls is discussed along with their impact upon the stability of processing. The history of studies on this issue is reviewed, and key technical requirements for devices of this type are identified.
