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.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
