| Abstract Scope |
A forging process planning method, including blanking and punching,
termed General Step Reduction and Enlargement (GeneSteR+E), is
discussed for cold- and warm-forged products. It is applicable to
non-axisymmetric forged products that consist totally of
non-axisymmetric shape elements, and can generate multiple process
plans without relying on design cases. The shape of a forged product
is split into outer and inner shapes, which are then split into
axisymmetric and non-axisymmetric shape representation units termed
basic elements (BEs) according to shape separation rules. Process
plans are generated in a reverse order from a final forged product by
applying shape transformation rules that reduce the number of steps
between BEs until a billet (or a blank) is obtained. The shape
transformation rules are defined not only for forging, but also
blanking and punching. An experimental knowledge base was implemented
and applied to several non-axisymmetric forged products, such as an
electrical connector. The results show that the GeneSteR+E method is
applicable to the design of forging process including blanking and
punching of totally non-axisymmetric products, and can generate
satisfactory process plans comparable to those developed by an
experienced engineer. |
