Automatic Optimization of a Complete Manufacturing Chain
Most forming processes are multi-stages processes.Typically,a standard forging sequence consists of three operations: Pre-forming,Blocker,Finisher,which are followed by heat-treatments.We call this the complete manufacturing chain.Simulation-wise,all these stages have to be computed one after the other; we call this the simulation chain.From the optimization point of view,it is quite challenging because the process parameters which could be modified usually belong to the early stages of forming (blocker) while the quality or non-quality of the formed part only appears during the last stage (finisher or heat treatment).For any modification on the early stage,all the following stages have to be re-computed to evaluate the benefit of the modification.This is time consuming and then often people renounce to do it.In this paper,we show how the concept of simulation chain used in the Forge software can be coupled with automatic optimization techniques to address this point.In order to get a smooth integration in the user workflow,all the geometries to be optimized (both initial shape of the part and dies) are generated and modified through CAD system driven by the Forge automatic optimization engine.
