GRACE Improves Production and Product Quality

09.04.2013
As part of an international project, software experts at Siemens' global Corporate Technology (CT) department have created a model that closely links the development of products with the machinery that will be needed to manufacture them later on.

The goal of the recently completed EU-supported project GRACE was to improve product quality by changing existing manufacturing processes only - i.e. without utilizing higher quality and thus more expensive materials, or new processes.



The CT experts succeeded here by analyzing how all individual aspects of factory automation influence the quality of the finished product. Using so-called multi-agent systems, the specialists came up with new approaches for product development, and their methods are now ready for practical application.

Continual measurements of product quality as early as during the manufacturing process provide important information on how to reduce rejects and lower throughput times. Such quality testing usually isn't possible in traditional factory automation systems because the combination of individual process steps cannot be studied as a whole. The new model is able to identify factors (and their causes) that have a major influence on product quality.

The six GRACE (inteGration of pRocess and quAlity Control using multi-AgEnt technology) project partners examined the production process for a washing machine. Using their model, the Siemens researchers were able to determine how the manufacturing process for a shaft that drives the spinner centrifuge influences the quality of that component. They found out that optimizing one step in the multistage production process could substantially increase the shaft's reliability and service life. Even minor changes suggested by the model can lead to significant improvements.

For example, the researchers modeled just five of the more than 100 individual parts of another washing machine component, and two out of more than 200 product functions - and just the associated optimizations proposed by the model reduced the share of component rejects from seven percent to less than two percent.

A practical industrial test revealed further optimization potential for an existing production line. Here, the model concluded that two quality control stations were no longer needed. Instead, two new control stations were installed to monitor quality on another part of the line. As a result of this measure, the time needed for functional tests of the washing machines was reduced by 30 percent.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
