Tóm tắt

This paper investigates cutting forces and surface error due to cutting force-induced tool deflections in peripheral milling of curved geometries. In machining workpiece geometries, where curvature varies continuously along the tool path, both cutting force and surface error vary from point to point. This is different from the case of machining straight and circular geomtries where cutting forces and surface error are both invariant along the tool path. To study the effect of curvature, first force models for feed and normal cutting forces are derived from dynamometer measured forces. These force components are used to calculate tool deflection and resulting surface error. The results of this study show that both cutting forces and surface error are influenced strongly by workpiece curvature.
