Abstract:For the existing troubles of carbide tool (serious tool wear,poor machining quality,low efficiency) when processing quartz fiber reinforced ceramic matrix composites,cutting force effect on the hole quality is analyzed in this paper by comparing the machining effects of carbide tool,PCD tool and electroplated diamond core drilling tool.The results show that the influence of weft fiber on the cutting force of X and Y direction is more obvious than that of warp fiber. The cutting force perpendicular to the weft fiber is smaller while the cutting force in parallel with the weft fiber direction is bigger.Moreover,the hole quality drilled by PCD tool is relatively better and the tool wear is not obvious,so PCD tool is suitable for processing the quartz fiber reinforced ceramic matrix composites.
