Bionics is a subject which can interact with many disciplines including the drilling engineering. On the basis of analyzing the properties of bionic non-smooth surface. the non-smooth theory is applied in the bit design to develop the bionic diamond bit. The dung beetle is selected as bionic prototype in this paper to design the working layer of an impregnated diamond bit. https://sportsplazanyes.shop/product-category/womens-tights-2/
