对化学镀NiP表面进行了微切削实验，以加工出微沟槽和微金字塔阵列等微结构。对不同条件下的毛刺形成行为和切削力特性进行了实验研究和有限元模拟。提出了一种简单的两步切削工艺，以提高表面质量。加工的微结构阵列被用作热压玻璃成型实验的模具，并证实了良好的几何转移性。本研究的结果验证了金刚石加工的NiP微结构模具适用于大规模生产精密微机械和光学元件的玻璃成型工艺。(C)2009爱思唯尔有限公司版权所有。
Micro-cutting experiments were conducted on electroless-plated nickel phosphorous (NiP) surfaces to fabricate microstructures such as microgrooves and micropyramid arrays. Burr formation behavior and cutting force characteristics were investigated experimentally and simulated by the finite element method (FEM) under various conditions. A simple two-step cutting process was proposed to improve the surface quality. The machined microstructure arrays were used as molds for hot-press glass molding experiments and good geometrical transferability was confirmed. The results from this study verify that diamond-machined NiP microstructure molds are applicable to glass molding processes for mass production of precision micro-mechanical and optical components.
