Silicon　carbide　ceramics　are　widely　used　in　many　industrial　fields　owing　to　their　outstanding　physical　and　chemical　characteristics.　However,　their　inherent　hardness　and　brittleness　make　the　grinding　process　very　difficult　compared　to　that　involving　ductile　materials.　In　the　present　study,　the　effects　of　the　biomimetic　fractalbranched　structure,　inspired　from　the　leaf-vein,　on　the　grinding　behavior　of　silicon　carbide　were　investigated.　Two　biomimetic　fractal-branched　structures　with　different　densities　of　micro-channels　were　designed　and　compared　with　the　non-structured　silicon　carbide　surface.　The　surface　of　the　silicon　carbide　ceramic　was　textured　through　pulsed-laser　ablation.　Thereafter,　the　grinding　experiment　was　conducted　on　the　biomimetic　fractalbranched　and　non-structured　workpieces.　The　surface　topography,　subsurface　damage,　grinding　force,　grinding　force　ratio,　surface　roughness　and　grinding　wheel　wear　were　examined　throughout　the　experiment.　The　experimental　results　indicated　that　the　normal　and　tangential　grinding　forces　for　the　fractal-branched　structure　surface　are　7.61-18.21%　and　8.34-26.13%　lower　than　those　for　the　non-structured　surface.　The　grinding　force　ratio　also　increased　significantly　with　an　increase　in　the　micro-channel　density.　In　addition,　a　larger　volume　of　coolant　was　transported　through　the　grinding　zone　of　the　fractal-branched　structure.　The　research　results　confirmed　that　the　biomimetic　fractal-branched　structure　on　the　silicon　carbide　surface　enhanced　the　grinding　performance　and　improved　the　grinding　quality.
