Beschreibung

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