Combining the experimental results and theoretical analysis, the following work has been accomplished.(1) Reasons of the decrease of interelectrode capacitance and the increase of discharge gap caused by the powder suspended in dielectric fluid are explained. And the mechanism that surface quality of workpiece improved by powder-mixed EDM is analyzed from this viewpoint.(2) The variation regularity of the percentage of silicon on the machined surface of workpiece has been summarized according to the experiment results when silicon powder was added into the working fluid. The entropy is introduced to explain the reasons for this variation regularity by thermodynamics.(3) The dimensional accuracy is greatly influenced by the overcut resulting from discharge gap and electrode wear in practice application. Empirical formulas for the overcut in EDM and powder-mixed EDM are established based on the experimental results using the ternary linear regressive method in this paper.(4) The influence of main factors on the machined surface characteristics has been evaluated based on the orthogonal experimental design method.

The experimental results show that the content of SiC in RBSC increases with carbon content while α-SiC is chosen as a filler. However, the residual carbon would appear in specimens when the carbon content exceeds 30% by weight. Using carbon felt, the reaction-formed SiC particles are small and uniform in size and distribution. However, when carbon felt is impregnated with phenol resin, the reaction-formed SiC is nonuniform in size and distribution. X-ray diffraction shows that the fabricated RBSC is composed of α-SiC,β-SiC, and free Si. The polytype of SiC is related to the reaction-heat during sintering.
