DFE
(DIE FACE ENGINEERING)
The eta/DYNAFORM-DFE module, Die Face Engineering, has
been developed to generate Die Face (Addendum and Binder) to support early
stage die design. In eta/DYNAFORM 5.6, DFE module has been updated to provide a
simpler GUI for the user to operate. In addition, with DFE module, the user can
import the part model and complete the whole process design quickly.
The functions provided in the eta/DYNAFORM-DFE module are
shown in Figure 6.1.
