After you have completely set up the press system (with tools), you can
calculate the deflection. This can be done based upon a normal press
sequence.
Select the "Curve Output" system function key.
Press a workpiece and record the force/stroke curve.
Enlarge the curve section so that the press start and press end are
visible.
