Simulation of metal cutting with cutting fluid using the Finite-Pointset-Method

Despite the common use of cutting fluids in metal cutting, most simulations of these processes only consider dry conditions. This is largely due to limitations in conventional simulation methods, such as the Finite Element Method (FEM), regarding fast changing computational domains. In this paper, a simulation model of metal cutting with cutting fluid based on the Finite Pointset Method (FPM) is presented. This approach allows to simulate the Fluid-Structure-Interactions (FSI) within the same simulation method. For different orthogonal turning processes, the simulations are compared with experiments for dry and wet conditions. The simulation results illustrate the cooling effect numerically.
