surface micro texture

In this paper, friction surface of broach is designed according to the idea of bionic micro-texture to achieve the purpose of reducing cutting force and improving cutting efficiency.

本文将采用仿生微织构的设计思想来设计这种拉刀的摩擦表面，以达到降低拉削力、提高拉削效率的目的。

Micro-analysis on test ring worn surface indicated that, to the composite reinforced by plain carbon fabric, the gap between the carbon fibers and texture provided by the plain fabric caused the oil infiltrate to the friction surface, improving the lubrication effect between the sliding surfaces.

试环磨损表面微观分析表明，平纹织物增强的复合材料，碳纤维之间的间隙及平织物形成的表面纹理使得润滑油能深入到摩擦试环各区域，增强了滑动面流体润滑效果。

The results show that micro-cycle grid texture sliding surface can decrease friction coefficient effectively, and the geometry parameters have couple effects on the lubrication characteristic. The theoretical approach established providing a rudimental method for optimizing the design of grid textured surface.

结果表明：具有微循环网格形态的滑动表面可有效地改善其摩擦系数，其几何参数对润滑的影响呈现互耦合机制；该研究可为滑动表面微循环网格织构优化设计提供理论基础。

In this paper, surface texture is described, especially for the micro texture, which pro-duced by means of ultra-pricision machining with PCD tool.
