2017/3/25The ZrB2-SiC-graphite composite is a promising engineering material for ultra-high temperature applications. However, the fabrication of micro-hole in this ceramic composite is difficult due to the high hardness. This paper presents micro-electrical discharge machining (EDM) drilling of the ZrB2-SiC-graphite composite using the micro sheet-cylinder tool electrode to improve the machining

Session 5 abstracts

Ceramic matrix composites (CMC) consisting of SiC fibers (SiC f) and SiC matrix receive attention as a material for next-generation aerospace engines due to light weight and high heat resistance. SiC f /SiC-CMC is fabricated by weaving the SiC fibers, followed by infiltrating SiC into their interstices.

Sequential micro machining (SMM) is a strategy of machining applied for micro-part manufacturing. Due to the finding of new sequential machining combinations, the authors have presented a novel combination of micro-ECDM (ECDM) drilling and micro-ECM (ECM) finishing for producing micro-holes in SS-304 stainless steel.
