Modular drive concept for self-propelled tools
The goal of the OBERON project was to use the lightweight construction concept to place a driven tool with small mechanical and structural dimensions in a decentralised manner within the tool. The focus here was on the individual controllability of the respective drives, which allowed for parallel operation. Different motion and load profiles had to be managed by the control algorithm in order to implement highly dynamic forming operations reliably. Relying on FE calculations for common manufacturing processes and subsequent experiments on the newly developed demonstrator tool, important statements regarding the feasibility and final implementation of a prototype solution could be made. As part of the project, a self-regulating tool with 4 decentralised individual drives for highly dynamic forming processes could be successfully implemented and tested.
