Abstract: The project will address the use of zero-point modular fixtures as a reconfiguration enabler in FMSs. This class of equipment provides the capability of rapidly reconfiguring the pallets to match the production requirements, without the need of halting the system for a setup, thus providing a strategic tool to manage the joint evolution of products and processes. The research activities will address the pallet configuration and process planning problem using a non linear and distributed process representation modeling a wide range of alterative operation sequences. Moreover, the problem of pallet checking will be considered using a laser scanning system able to verify the correct configuration and load of the pallet. Finally, the effectiveness and benefits of zero-point modular fixtures will be assessed evaluating their impact on the performance of a FMS and providing managing policies to exploit the available degrees of freedom. All the activities will refer to an industrial case.
Ideas and solutions:
Pro2Evo addresses a set of barriers preventing the use of zero-point clamping as a tool for fast pallet reconfiguration:
A Conceptual Framework to cope with the evolution of products and with a specific focus on the re-configuration of fixtures, setup-planning and system’s performance. Pallet verification and check devices (e.g. a 3D laser scanner) and tools to check the compliance of the pallet with the ideal configuration. A Network Part Program definition providing modular machining processes. A Data Model to support information and data management and the compliance with standards. Management policies to take advantage of the fixture reconfiguration at the operational level.
Pro2Evo gave rise to the prototype project Pro2ReFix (Product and Process Co-Evolution Management via Reconfigurable Fixtures) aimed at demonstrating 1) the use of zero-point clamping to provide fast reconfiguration of pallets and fixtures; 2) how pallet check functionalities can be implemented and work in a realistic environment, 3) the exploitation of process plans available in modular format to provide a fast reconfiguration of the machining processes together with the pallet.
