Electrodischarge Machining an overview ScienceDirect

Miniaturized EDM or in other words micro-EDM can be classified as micro-EDM by die-sinking, micro-wire electrodischarge machining (micro-WEDM), micro-electrodischarge grinding (micro-EDG), micro-wire electrodischarge grinding (micro-WEDG), etc., with respect to the applications and types of tool used. High machining accuracy can be realized by introducing a precise mechanism for the moving

Effect of Complex Electrodischarge Grinding for

In this study, investigation is made on effective grinding condition to realize high efficiency, low and stable grinding force and low wheel wear in complex electrodischarge grinding. As a result, superior grinding property was obtained when the grinding wheel was set at minus polarity, and set peak current of iP = 4 and 6 A was applied. Furthermore it also became clear that additional

In electrodischarge sawing (EDS), surface roughness for high feeds is 10-12.5 pm, while at lower ones it is 6.3-10.0 pm. The depth of the recast layer is about 0.025 mm deep. Similarly, tolerances of ±0.076 to ±0.4 pm can be achieved depending on the feed rate. Figure 9.6 depicts surface roughness and tolerances for some thermal machining processes.
