ProFlexA — Productive Flexible Automation
Researchers: Rolf Johansson, Anders Robertsson, Olof Sörnmo and Björn Olofsson in cooperation with Dept. of Computer Science, Lund University and Div. of Assembly Technology, Linköping University and several industrial partners.
Funding: This project is financially supported by the Swedish Foundation for Strategic Research (SSF) under the programme ProViking.

The Swedish casting and foundry industry is under high pressure to reduce its production cost in order to maintain its competitiveness and avoid moving its activities to low cost countries. This means that there is a need to improve efficiency, product quality and consistency and to reduce costs and lead-time. The project focuses on achieving productive and profitable robotized automation of the fettling for small and medium sized volumes.
The project has the following work packages that also reflects the expected results and deliverables.
- WP1: Development of components and methods for handling of castings, including development of modular, configurable, simple and inexpensive grippers.
- WP2: Development of technology and configurators for flexibility and quick start-up of new products or product changes.
- WP3: Development of methods for measurement of excess material and compensation of gripper errors.
- WP4: Build-up of database of process parameters for optimal material removal rate.
- WP5: Development of a Lead-through programming concept.
- WP6: Development of the Off-Line programming concept.
- WP7: Development of physical demonstrator.
- WP8: Exploration of the potential for the developed technology in other industry branches.
All of these benefits strengthen Swedish foundry industry and delivers important knowledge to other adjoining industry sectors.
