Multi-phase numerical simulation of coolant flow around the cutting tool

The thermal behavior has a significant effect on the manufacturing accuracy. For many machining tasks, the use of cooling lubricant is essential in order to achieve possible cooling and lubricating effect in the cutting zone. Its reduction due to resource-efficient or ecological efforts has an impact on the temperature field in the machining tool, which affects the thermal behavior of the frame structures and can cause machining inaccuracies. This article describes the CFD-model for simulation multi-phase flow of liquid coolant around the cutting tool and the prediction of the temperature field. With experimental investigations, the simulation model is verified and checked for plausibility.
