|Coordinator||Swerea IVF AB - Avdelningen för processutveckling|
|Funding from Vinnova||SEK 3 900 000|
|Project duration||October 2015 - May 2019|
|Venture||The strategic innovation programme for Metallic material|
Purpose and goal
The project will result in a generic methodology for virtual die compensation of press tools with respect to thinning and shape deviation. Research activities rare elated to material and friction modeling includes variable friction conditions, elastic tool deformation and heat transfer in the contacts. The project aims to achieve a high accuracy in product design and process development of lightweight components with short lead times. Newly developed highly advanced carbon and stainless steels for lightweight components are studied as well as the 7000 aluminum.
Expected results and effects
The methodology enables to further strengthen the prediction accuracy of computer simulations to develop sustainable sheet metal forming processes and to manufacture tools based on virtual models and thereby reduce time-consuming die try-out and manual tool spotting. The methodology is of interest to companies that develop, manufacture and use sheet metal forming tools or products. The goal is to increase accuracy, shorten lead time for both components and process development of lightweight structures and also increase the eco-efficiency by 30% compared to current practices.
Planned approach and implementation
The strategy of the project is based on initiation of industrial development needs with support of academic research. An industrial application is identified. The conditions for production stamping methods and functional requirements of the demonstrator are specified in detail. Modeling and analysis prerequisites are identified, possible material and friction models suitable for the selected materials and process conditions are proposed. Model parameters are identified, virtual tool compensation is performed together with validating friction and stamping experiments.
