Numerical and experimental investigation on the flow behavior of liquids in narrow gaps
Abstract: Lapping is one of the manufacturing processes with geometrically undefined cutting edges and is used to produce technical surfaces with high dimensional and shape accuracy. In order to predict the surface generation, a process model is developed that combines models of the material removal mechanism, the kinematics of the lapping particles and the flow of the lapping fluid. Due to many interactions in the process and the inhomogeneous flow of the lapping fluid (loose lapping particles in the fluid) a multiphysical model is needed. In a first step, only the flow behavior of the fluid without and with a simplified lapping particle (cuboid) is numerically and experimentally investigated. Particle Image Velocimetry is used to measure the flow field in the gap. The distance between the two plates, the velocity of the upper plate and the cuboid size can be varied. The experimental setup is simulated using a CFD model. Analogous to the experiment, the velocity of the upper plate and the cuboid size are also varied in the numerical study and the results agree well with the measured flow field. The CFD model helps to analyze further parameters, such as the influence of workpiece velocity on the flow. In the future, the model will be used to analyze the interaction between lapping particles and lapping fluid, which is very important for studying the mechanisms of material removal during lapping.
