The Effect of EDM with external magnetic field on surface roughness of stainless steel

During electro-discharge machining (EDM), debris particles are generated in the machining gap from the eroded materials. If they are not quickly removed, arcing would occur, and this reduces the machining efficiency. The introduction of external magnetic field (EMF) is a research innovation which tr...

The highest duty factor of 56% also produced the roughest surfaces in the two machining schemes under the highest peak current. 2013-07-03 Conference or Workshop Item PeerReviewed application/pdf en http://irep.iium.edu.my/35242/1/programbookiec.pdf application/pdf en http://irep.iium.edu.my/35242/2/Front_page.png application/pdf en http://irep.iium.edu.my/35242/3/2013%2C_ICMAAE%2713%2C_Baba%2C_30012.pdf Khan, Ahsan Ali and Ndaliman, Mohammed Baba and Mohammad , Yeakub Ali and Al-Falahi, Muath D. and Ibrahim, Haazin A. and Mustapa, Mohad S.
