The machining parameter used to machine the sample with Taguchi Method are electrodes (Copper and Copper Tungsten), current (3A, 6A, 9A), polarity (positive or negative), and dielectric fluid (Kerosene, Amoil, Novis), as well as Capacitance (OuF, 3.3uF and 10uF). All the effects on the parameter used will be discussed in term of surface roughness, roundness, hardness, microstructure and white layer thickness. Based on the result obtained, when high current is used, the machined surface will be rougher and the depth of cut is deeper because the MRR is higher. In term of polarity, positive polarity always will better surface finish compare to negative polarity but the machining time will be longer. 2009 Thesis https://ir.uitm.edu.my/id/eprint/31330/ https://ir.uitm.edu.my/id/eprint/31330/1/31330.pdf text en public degree Universiti Teknologi MARA Shah Alam Faculty of Mechanical Engineering Mohd Abbas, Norliana
