Abstract

Complex three-dimensional miniature components are needed for a wide range of industrial applications from aerospace to biomedicine. To fabricate these products, micro-end-milling that can accurately produce a high aspect ratio part is being actively researched. This paper presents a mechanistic cutting force model that can precisely predict the cutting forces in micro-end-milling under various cutting conditions. The model uses instantaneous cutting force coefficients that are independent of the end-milling cutting conditions and reflect most of the cutting mechanism involved in micro-end-milling including the minimum chip thickness effect. Comparison of the predicted and measured cutting forces showed that the proposed method provides very accurate results.
