Shear-slitting process is used to separate sheets which are produced in large rolls that need to be cut to specific dimensions to make final products. The high residual stresses, sheet deformation, secondary fractures and burr formation at cut surface during the cutting or slitting processes leads to deterioration of quality of workpiece. The paper focuses on the numerical and experimental analysis of slitting process using FEM, SPH and vision-based methods. In computer models dynamic effects, mechanical coupling, constitutive damage law and contact friction are taken into account. The effect of main process parameters on equivalent plastic strain state and burr formation on cut surface of aluminum alloy is analyzed. The results of computer simulations can be used to forecasting quality of the final parts optimization. [ABSTRACT FROM AUTHOR] |
