Siemens UK deploys Virtalis technology for digital factory
13 June 2016
Siemens UK has installed Virtalis Virtual Reality (VR) systems and software in its Congleton factory as part of its drive towards the Digital Factory.
Carl German, a Siemens’ transformation manager, explained “our VR has been a game-changer for us and how we work. It’s no exaggeration to say it has changed the way we think and act. Every single production operative in the factory has either seen or experienced it. It’s key that the technology is not seen as something for a privileged few. As a result, we now bring VR into every facet of what we do.”
Siemens embarked on its VR journey with a clear vision of what it wanted to achieve:
• Simulating and optimising assembly processes
• Effective factory planning
• Efficient design concepts and reviews
• Lean work-cell design
Simon Charlson, mechanical team leader at Siemens, was heavily involved in researching the kind of system and software that could fulfil the company’s needs. “Our first thought was a multi-walled Cube, but the product review and Lean Cell Design teams are up to ten strong, so we went for a bigger Virtalis ActiveWall with a projected wall and floor combined with optical tracking for group and collaborative activities and a Head Mounted Display-based Virtalis ActiveSpace for additional levels of immersion.”
Siemens’ Digital Factory in Congleton, Cheshire, designs and manufactures variable speed drives for motors. Its customers come mainly from the automotive sector, machine building (OEMs), pumps and fans and the airport industry. The drives control the speed of the motor, increasing efficiency of operation and decreasing power use. Although there are only five decentralised product ranges and four cabinet based systems, the inherent modularity of these drives, plus the many different frame sizes, mean that there are thousands of potential product configurations. “It is costly to create the tooling to manufacture a new product”, explained Simon, “and mistakes tend to be expensive. We are now working with our suppliers to bring their virtual tooling into our design reviews. We are finding that this agile development is resulting in great communication between mechanical, electrical and design engineers and is shortening lead times.”
Adrian Webster, Siemens’ layout planning engineer, commented “VR removes the big issues early on and lets us concentrate on simple refinements. Typically, we build a mock-up of a new cell on the factory floor. Previously, we would need to leave it there for four weeks to resolve all the issues. Now, we are finding two days’ digital review plus just one week on the factory floor solves all the issues. VR is excellent at fostering multi-disciplinary communication. The people who have input into new designs are diverse: production engineers, test engineers, production operatives and production leadership. Sometimes they obtain extra expertise from R&D or from mechanical and electrical engineers too, or even logistics and facilities people and contractors. All these stakeholders work together in the VR environment to perfect the design and get the requisite buy-in.”
Siemens has also diversified its use of the VR technology and is using VR for everyday uses, such as office moves. Here, Adrian finds that Virtalis’ Visionary Render software is ideal. “It is intuitive and anyone can get the hang of it quickly to navigate round the model, so I can help people visualise their new working environments. I am also finding Visionary Render is superb for setting up animation sequences and for demos.”
The Siemens team is finding that the Virtalis VR is saving them money by enabling the virtual interrogation of belts and driving mechanisms, for example, as part of OEM production equipment specification, resulting in demonstrably fewer mistakes. A recent VR design review picked up a clash within two minutes that had not been clear on a CAD workstation.
Anil Thomas, a transformation manager at Siemens, commented that “typically, we’re finding that we are reducing the snagging list of a new cell design by 90 percent. We are even finding more and different snags virtually and solving them in VR. This will certainly have a positive impact on our product lifecycle. We are not resting on our laurels, as it is apparent there is much more we can do with this technology. We’d like to work with Virtalis to create a roadmap to incorporate real-time collaboration with other Siemens factories around the world as well as haptics and motion capture.”
