Numerical and experimental analysis of machining of Al (20 vol% SiC) composite by the use of ABAQUS software

In this study two-dimensional finite element model of Al/SiC metal matrix composites (MMC) are investigated by the use of ABAQUS/Explicit software. Chip formations and machining forces during machining of MMC have been studied and compared to experimental data. It was found that the resulted chips in simulation and the generated chips in experiments both have saw-tooth in appearance. On the other hand, the obtained cutting forces diagrams from simulation and experimental conditions have considerable fluctuating with passing cutting time. This is due to the interaction between tool and SiC particles during chip formation.
