“…Below a supply pressure of p = 1000 bar, the exerted force of the cutting fluid jet is not sufficient to change the conditions of friction significantly. Therefore, the changes of the cutting force when using HP CF compared to flood cooling are relatively small [11] [24].…”

“…In these terms, high-pressure cutting fluid (HP CF) [10] [11] and cryogenic cooling lubrication (CRYO CL) [12] [13] have proven to be effective alternatives. The HP CF strategy uses cutting fluids at high pressures and flow rates focused towards the cutting edge in order to maximize their effectiveness [10].…”

“…For both cooling lubrication technologies, a scientific understanding of their cooling lubrication mechanisms, thermal and tribological effects determines their exploitable potential for an efficient machining of difficult-to-cut materials [10] [13]. An essential first step in this scientific analysis is the quantification of the cooling effect of HP CF and CRYO CL in relation to the dissipated heat from the cutting zone in order to maximizing metal-cutting performance and optimize tool designs [11] [14]. Both scientific knowledge regarding the underlying mechanisms, as well as the practical quantification of cooling effect are mostly missing for milling applications.…”

“…The main functions of MWF are cooling and lubrication. Temperature reductions in wet machining processes compared to dry processes were presented by various authors and can be attributed to several effects, e.g., reduced friction and heat absorption of the MWF [2,6]. The influence of MWF on friction is often investigated on tribometers.…”

Metal working fluids are used in machining processes of many hard-to-cut materials to increase tool life and productivity. Thereby, the metal working fluids 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 effects is challenging, since a detailed look at the chip formation process is prevented by the metal working fluid. 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 fluids. Experiments reveal that process forces are reduced with increasing pressure of the metal working fluid. However, the average friction coefficient only changes slightly, which indicates that the reduced process forces are mainly the result of reduced contact lengths between rake face and chip.
