DESIGN OF WINDING WITH TWO ROVINGS FOR COST EFFICIENCY AND QUALITY IN ROBOTIZED FILAMENT WINDING

摘要

This work deals with the design of winding with two rovings of asymmetric and complex shape parts by means of robotized filament winding technology. The adopted criteria aim to decrease significantly the winding time and, therefore, the manufacturing costs by preserving the composite part quality through the design of a system that is able to control the orientation of both the rovings on the die during winding, thus avoiding their torsion. A cell composed of an industrial robot opportunely equipped with a new feed and deposition system has been designed and implemented. Two rovings are unwound by two spools fixed to a creel and, then, they are conveyed towards the new feed and deposition system connected to the robot end-effector. The rovings pass through the roving-guide system, where they are paired off in a single roving that is guided towards the deposition head. The deposition head controls the orientation of the single roving on the die during winding. The new system working and its interaction with the most critical process parameters have been evaluated through experimental tests. This work belongs to a research project aiming to develop an integrated environment to wind complex shape parts through a robotized cell.
