Simulation of stationary sheet metal cutting processes

摘要

In stationary sheet metal cutting processes, like guillotining and slitting, the sheet is cut progressively from one end to the other. This in contrary with transient processes (blanking) where the sheet is cut at once. Where transient shearing processes can be modeled in 2-D (plain stain strain or axisym.), stationary shearing processes have to be modeled in 3-D. For the calculation of the steady state of the guillotining process a 3-D finite element model is developed. Also plane strain shearing simulations are performed. The Arbitrary Lagrangian Eulerian method is used for all simulations. The results of both cases are presented and compared with each other.
