SIVPRO – Shape Inspection by Vision in PROduction

Project time: 2014 – 2017

Budget: 7 049 994

Funding: SIP Produktion2030

Purpose and goal

The purpose of this project w as to perform an industrial demonstration of a system for automatic control of the geometry of produced components where the components are transported on a conveyor belt. This objective has not been reached. How ever, a number of technical objectives regarding the performance of the system are verified and to some extent even been surpassed. Today w e have a system that manages to control the shape of manufactured components, moving freely on a conveyor belt, w ith sufficient precision. The system manages a component frequency of 0.5 Hz.

Results and expected effects

The identified main effect once the system is installed w as a reach a 20% reduction in scrap rate. In addition w e also foresaw a significant effect on the natural variation of geometrical outcome, increased availability of process stage, decreased w ear and need of maintenance, increased control of produced items, and significantly reduced run-in times. None of these effects have been verified, which also w eren’t expected. Instead a number of technical demands have been verified that may result in the fulfilment of these effects provided the system is properly used.

Approach and implementation

This project has been a cooperation betw een three academic partners and five companies. The academic partners w ere responsible for the evaluation softw are, system integration and analysis, respectively, while the companies represented different parts of the technology. One of the companies w ere an end-user. The project w as redundant in the sense that tw o different measurement technologies w ere provided by tw o different companies. The biggest obstacle in the project turned out to be that none of the partners had a total technological concept, which lead to blocking.

Secure Shortcut (See Cut)

SeeCut focuses on cost-efficient production systems for secure collection, analysis, visualization, storage and sharing of production data. The project addresses the integration of new signals and sensors. For advanced products, like jet engine components, collecting data during manufacturing and usage is essential for quality assurance and remanufacturing. The project goals are to identify key technical requirements related to production data for use in digitalized value chains, define means to ease the run-time integration of new signals and data streams from manufacturing machinery and sensors, and define how to securely and cost-efficiently share data through the value chains in circular production.

Tailored Tool Surfaces for Robust and Sustainable Hot Stamping

Tooling constitutes a significant part in the economical investment of the hot stamping process. Significant benefits in production economy and environmental benefits can be attained by improving the tribological performance in hot forming operations of automotive components. The main idea of this project is to create tailored tool surfaces on dies made from cheaper and easier to manufacture tool steel for the hot stamping of ultra-high strength steels.
