The percentage error between the experimental and predicted cutting forces and chip geometry is lower than 5% and 30%, respectively. In general, both models show a great capability of modeling the cutting process. The validation of the proposed models is carried out by comparing the predicted results with the experimental evidence. A proper user subroutine is developed to apply the heat transfer by convection induced by the fluid. The mechanical and thermal effects induced by the coolant are investigated apart. The simulation results are compared to analyze the advantages and limitations of the two simulation methods.
The models combine the Lagrangian approach to model the structure and the SPH/Eulerian approach to model the fluid. Two simulation methods are developed in the commercial finite-element code ABAQUS/Explicit: the coupled Smoothed Particle Hydrodynamics–Lagrangian (SPH-L) approach and the coupled Eulerian–Lagrangian (CEL) approach. The aim of this work is to investigate a fluid–structure interaction problem, in which the chip formation and the fluid flow are coupled.
