Modem systems for the development and manufacturing of new products are str
ongly connected to market demand. To achieve fast and effective response to
market needs, the concept and design phase must take place in a virtual CA
-x environment.
Once the approximate product geometry is known, a numerical simulation has
to be performed to study the forming process and appropriate tool design. A
fter some iterations, product geometry, with some variants, is known and th
e best of them is chosen for further development. The number of stamping st
eps and the exact tooling geometry are determined.
The stamping processes which are widely used in the manufacturing of sheet
metal parts are hard to control, since they depend on numerous parameters r
elating to geometry and material type. The purpose of this paper is to pres
ent the industrial application of 3D numerical simulations using the PAM-ST
AMP program in the product and process development cycle.
The simulations were performed during product and process development inclu
ding tool design and manufacturing. The issues theoretically discussed in t
he first part of the paper will be explained by example. The time, costs an
d benefits analysis of using the numerical simulation in the product and pr
ocess development cycle will also be discussed. (C) 2001 Elsevier Science B
