Hello,
While calculating the actual draw tonnage for the setup given in (ref.) IMAGE 1 ( O.K. in FLD & %Thinning), I have following doubts in calculation of the tonnage calculation in HyperGraph as:
1. In forming setup the binder force is 15T is used, but in the hypergraph it is showing more that 20T , so which should be consider as actual or required binder force to freeze the model setup?
2. How to calculate the actual Draw tonnage from the die(upper steel) & blank contact graph as shown in the IMAGE 2, i.e. which of the following point should select to define the required draw tonnage from die(upper steel) & blank contact curve (Ref. IMAGE 2)=
A. At the End point i.e. complete bottoming stage?
or
B. At the Point where maximum tonnage is showing in the graph for the die(upper steel) & blank contact curve?
