This invention provides a method for electro-discharge assisted flying cut machining of polycrystalline SiC thick films, comprising the following steps: etching the surface of the polycrystalline SiC thick film using electro-discharge machining to form a pre-treated polycrystalline SiC thick film with a microcrack network; and finishing the surface of the pre-treated polycrystalline SiC thick film using diamond flying cut to obtain a finished polycrystalline SiC thick film with a nanoscale surface.
