Abstract
A method for simulation-based analysis of the 3D fluid dynamics of a coolant lubricant in the saw tooth space is presented. The examination serves on the one hand to characterize the flow around the bounding surfaces of the narrow-closed cutting gap regarding the local flow conditions. On the other hand, the outflow behaviour of the coolant lubricant out of the narrow-closed cutting gap is analysed to get a deeper understanding of the cooling mechanism. Therefore, the model design is described considering the computational domain and the boundary conditions. Finally, an evaluation method for the local flow behaviour at different surfaces and the coolant lubricant outflow of the tooth space in the narrow-closed cutting gap is illustrated.
