Lecture 24. Wire-cut EDM or Wire EDM (WEDM), also known as Spark EDM is mostly used when low residual stresses are required, as it does not needs high cutting forces for removal of material. The spark generated by this process produces heat, which remove metal by erosion and evaporation. wire EDM, AWJC 5 Micromachining. Sasa Zivanovic, Radovan Puzovic . Taper cutting with wire EDM can be done accurately and efficiently as long as the proper systems and techniques are used. 0000004017 00000 n ⁄ cut across flux lines, hence, voltage builds, reaching a peak when flux is cut at the maximum rate in the 90 P ° position as in (b). A separate EDM head specifically for small hole drilling is mounted on a wire-cut machine and … Wire EDM is also known as: wire-cut EDM, wire cutting, edm cutting, wire burning, wire erosion, and ‘cheese-cutter’ EDM. This history of wire EDM is less clear cut than die sinker EDM, but what is known is that it was developed over roughly a decade between the 1960s and 1970s as a new method for making dies from hardened steel. 0 �cFj endstream endobj 1530 0 obj 1104 endobj 1531 0 obj << /Filter /FlateDecode /Length 1530 0 R >> stream Conventional EDMs come in two forms, Sinker EDM and Wire EDM.
