摘要：

This paper is to explore the feasibility of TiN/Cu-based composite materials as electrical discharge machining (EDM) electrodes. The tool wear ratio (TWR) of EDM electrode directly reflects the machining precision. To reduce the tool wear ratio(TWR) of Cu electrode in the EDM processing, Inorganic mixture of different content of ceramic materials TiN powder and Cu powder are prepared, then pressed and sintered into EDM electrodes Experimental results show that: in the six batchs of experiments, the tool wear ratio (TWR) of 35%TiN/Cu electrode is the least, which is about 4.98%, much less than that of commercial copper electrode. The microstructures of the TiN/Cu electrodes after electrical discharge machining (EDM) as well are analyzed in this paper.
