Abstract [en]

Manufacturingcompanies continually need to develop and produce products faster, cheaper,and of better quality to meet requirements from customers andinvestors. One key factor in meeting these requirements is theefficiency of the product development and the production preparation processes.Design automation is a powerful tool for increasing the efficiencyof these two processes. The benefits of automating manufacturability analyses,a part of the production preparation process, are shortened leadtime, improved product performance, and ultimately decreased cost. Further, theautomation is beneficial as it increases the ability to adaptproducts to new specifications since production preparations are done infew or in a single step. Extruded sections of aluminum(aluminum profiles) have many advantages, especially for light weight structuralmembers, and are used in many products. Many times asecondary forming process, such as bending, is required when thesematerials are used. The intention of the work presented inthis article has been to investigate how to automate theprocess of finding manufacturing limits of the rotary draw bendingof aluminum profiles with focus on the system architecture neededto make such systems flexible. Finding the forming limits ofan aluminum profile is not a trivial task. This isbecause the limits depend not only on the profile shapebut also on the layout of the tool. Hence, simulationshave to be done to evaluate different designs. A prototypesystem was developed to explore what was needed to automatesimulation of the rotary draw bending of aluminum profiles, andsubsequently, analyze the simulated production outcome with respect to wrinklingand developed length.
