Simulation of Two Side Direction Burr Formation

Two side direction burrs is an important factor of influence to edge quality and performance of precision parts. A finite element model was developed for simulation of two side direction burr formation process. Based on strain distribution, a two side burr formation mechanism was proposed. Strain of Cutting lay material near the side face in two side direction of work piece is determinant factor of two side direction burr. Burr form and burr size of simulation are close to that´s of experiment. Finite element model generated here provided a numerical analysis method to solve the prediction of burr formation and physical insight into the fundamental burr formation mechanism.
