Influence of metal working fluid on chip formation and mechanical loads in orthogonal cutting

Abstract Metal working fluids are used in machining processes of many hard-to-cut materials to increase tool life and productivity. Thereby, the metal act on thermal mechanical loads tool. The changing can mostly be attributed friction between rake face chip changes formation, e.g., contact length chip. However, analyzing those effects is challenging, since a detailed look at formation process prevented by fluid. In this paper, novel planing test rig presented, which enables high-speed recordings force measurements while using fluids. Experiments reveal that forces reduced with increasing pressure average coefficient only slightly, indicates mainly result lengths
