Electrical discharge machining of ceramic matrix composites with ceramic fiber reinforcements

Electrical Discharge Machining of Al(6351)–SiC–B4C Hybrid Composite

“…Rahman et al [7] determined the influence of the process parameters on the MRR in the EDM of titanium alloy using copper as electrode and reported that pulse on time and current are the major influencing parameters on the MRR. Chenjun Wei et al [8] evaluated the EDM of SiC fiber-reinforced composite and understood that the high gap voltage and relatively small duty ratio are desirable for efficient material removal. Gopalakannan and Senthilvelan [9] investigated the influence of the process parameters on the EDM studies of B 4 C-reinforced aluminum matrix composite and reported that the two significant factors that affect the MRR are pulse current and pulse on time.…”

Micromachining features of TiC ceramic by femtosecond pulsed laser

“…In addition, there are inherent problems associated with such micromachining process for conductive ceramics. It is reported that a heat affected surface layer with poor surface integrity was created by EDM in alumina matrix composite [9] and silicon carbide matrix composite [10]. USM is a valuable process for the micromachining of nonconductive brittle materials.…”

Optimization of EDM Parameters on Machining Si3N4–TiN Composite for Improving Circularity, Cylindricity, and Perpendicularity

“…The machine should work effectively on conductive electrical pieces regardless of their mechanical properties and shape spark eroding processes [1][2][3][4].…”

“…Precisely, an orthogonal array and the grey relational analysis are employed to achieve the optimal parameter combinations [12,13]. Additionally, the Taguchi grey relational analysis (TGRA) and ANOVA are used to analyse the importance of machining parameters [3,8]. Chiabert et al.…”
