【正文】 ravel another mm before it should stop. Set a primary die displacement stopping control of 270mm in the Zdirection to stop the simulation when the mechanical press hits bottom dead center. Positioning the Top Die ? Position the top die so that it is in contact with the top of the billet. ? Revisiting InterObject Boundary Conditions ? For both relationships, assign a Hot fing (lubricated) friction of and a Forming heat ? transfer coefficient of 5. Generate contact between the billet and the dies. Running the Transfer Operation ? Operation Name: Transfer2 ? Operation Number: 4 ? After the first forming operation, simulate the transfer to the second station. Total time is 3 seconds. Use 6 steps at seconds/step. Write the database, and run the simulation. Running the Second Forming Operation ? Operation Name: Finish ? Operation Number: 5 ? For the second forming operation, it is necessary to import new tool geometry: ? Top: ? Bottom: ? For each of the geometries, define the two symmetry planes in the Symmetric surface tab of the Geometry button. ? Reset movement controls and set new simulation controls. For a plex forming operation, 200 time steps is reasonable. ? Set the stopping load to N. ? Write the database and run the simulation.
