Abstract

Mechanical micro-machining process such as micro-milling process is a promising fabrication process allowing miniaturization of conventional products and innovation of brand new micro-products. The advance of mechanical micro-machining process ultimately depends on the development of cutting tool since it is a tool-based process. Therefore, in this study an attempt to improve the performance of carbide micro-end mills using cBN coating was carried out. The 2-D finite element modeling (FEM) was used to simulate the effects of cBN coated micro-end mills in micro-machining of Ti-6Al-4V. Cutting forces, tool and workpiece temperature and tool wear obtained from FEM simulations were studied. Experiments were also conducted to verify the simulation results. The study clearly showed that cBN coated carbide tool outperformed the uncoated carbide tool in terms of tool wear surface roughness and cutting temperature.
