Finally, the 3D geometry entity model of gear was got.2. From the view of bionics principle, nine kinds of bionic non-smooth concave surfaces with different sizes and distance of non-smooth units were designed.
Usingoptimumdesign for experimentscheme, lasergraphictexturingwas adopted to formbionicnon-smooth microstructure on the gearsurface to studyanti-wearcapabilityof the gears.
