Siemens PLM Software helps guide new Manufacturing and Design Innovation Institute on quest to revitalize U.S. manufacturing

Siemens – U.S. President Barack Obama announced the launch of a new Manufacturing and Design Innovation Institute, also referred to as the Digital Lab for Manufacturing. It will be a world-class, flagship manufacturing hub drawing together the capabilities, innovative thinking and collaboration needed to transform American manufacturing.

The winning bid for a Department of Defense grant to create the lab was led by UI Labs–a Chicago-based research and commercialization collaborative that brought together 40 industry partners, more than 30 academia, government and community partners, and more than 500 organizations to develop and support the project. The Digital Lab will be housed in Chicago with a network of manufacturing partner and research sites across the United States.

The lab is part of the Obama administration’s planned National Network for Manufacturing Innovation (NNMI), built to accelerate development and adoption of cutting-edge manufacturing technologies. The network will encompass a series of regional hubs, all committed to finding ways to reinvigorate U.S. manufacturing, create new jobs, increase economic development and spur future innovation–to turn U.S. regions left behind by globalization into global centers of high-tech jobs.

Siemens PLM Software has been working closely with UI Labs to put together the winning proposal and will be one of six Tier One partners who will provide guidance and resources to UI Labs as the project moves forward. It is the only PLM software provider in this top tier. The other Tier One partners are Dow, General Electric, Lockheed Martin, Procter & Gamble and Rolls-Royce. more> http://tinyurl.com/kmgques

How LMS Virtual.Lab helps engineers capture real-world behavior

SIEMENS – Car in 3DEngineers around the world use computer-aided design (CAD) and computer-aided engineering (CAE) software to create, modify, analysis and optimize product designs. The basic principle is to capture real-world behavior literally on the screen or, in other words, make the virtual as realistic as possible.

This is quite a challenge if you think about it.

How would you go about designing a next-generation car or airplane?

How would you refine traits like acoustic performance or durability?

How could you be certain that the virtual product really will work as designed?

Engineers start from CAD to define the geometry and then move into LMS Virtual.Lab to refine the design using information from the physical world. This might be data acquired from theoretical assumptions or real-world testing. Test experts can use solutions like LMS Test.Lab and LMS SCADAS hardware to gather and crunch data, which is then used in calculations to refine the final product design.

Decades of software and solver development efforts have gone into LMS simulation solutions like LMS Virtual.Lab, LMS Imagine.Lab and LMS Samtech to help engineers answer tough questions like these. As a simulation tool designed to work with major CAD programs, LMS Virtual.Lab focuses on one idea: capturing true real-world behavior.

To give a more technical explanation, users can integrate data taken from real-world models into the simulated design, bridging the gap between the virtual and the real. In other words, engineers can re-use information from the test side of things to make better models on the simulation side. more> http://tinyurl.com/pjk5rvd

New ISO standard streamlines the collaboration in ship lifecycle

SIEMENS – Data, knowledge-sharing and collaboration are bigger challenges in the shipbuilding industry than other industries. Complications come from large amounts of data, different design and manufacturing stages, different disciplines and different software. Further adding to the challenges are the huge supply chain which includes design agents, equipment manufacturers, block fabricators and more.

More recently, with the expanding worldwide collaboration network which is resulting in design, engineering and manufacturing in extended enterprise, the shipyard and its entire supply chain has to manage this complexity of communication in a heterogeneous environment.

To support this, there is a need for a product representation method which can meet the demands of application and hardware independence, support the total lifecycle of a ship, generate viewpoint-specific representations, and rapidly share information between geographically-distributed applications and users while protecting corporate intellectual property.

Siemens PLM Software’s JT™ technology has been approved by the International Organization for Standardization (ISO) as an International Standard (ISO 14306:2012). JT provides a lightweight data format for 3D product information visualization and collaboration.

Because of JT, shipyard manufacturers, suppliers, even IT vendors and academia can work together to speed up the development of ship.

JT as a neutral lightweight format can handle several processes in design, construction and lifecycle support for the shipbuilding industry:

  • Program and project management
  • Collaborative design and engineering
  • Ship digital construction
  • Supplier chain management
  • Services and supports

The applications of JT go beyond visualization, so it is possible to optimize product engineering processes by integrating a JT-based solution into selected processes. Shipyards can use a combination of JT-supported processes along with processes which need the use of native computer-aided design (CAD) tools or various PLM systems.

Leading shipbuilders have already adopted JT technology in the development and manufacturing process of ship. more> http://tinyurl.com/motmqst

Siemens researcher prints Christmas trees from gas turbine steel

SIEMENS – Temperatures inside gas turbines can reach 1,400 degrees Celsius or more. The hotter, the higher the energy yield. The special steel that Rehme uses for his personal project of printing Christmas trees is a nickel alloy. It starts to melt at around 1,300 degrees Celsius and can be used, for example, for the burners in gas turbines. Steels that are even more resistant are used for the hottest turbine parts. Rehme gets the print data for his trees from the website grabcad.com.

High centrifugal forces: Heat isn’t the only thing impacting the steel
To generate electricity, turbines have to turn. And turn fast. Turbine blades also have to turn, exposing them to massive centrifugal forces that place high demands on the ductability of their materials. 3D printing with metals can’t yet meet these demands. For the little steel-hard trees, however, the technology is sufficient.

Layer by layer: The fine structure has to be ground down
If you look closely, you’ll see the printed tree’s fine structure. To make the surfaces completely smooth, 3D printed materials sometimes need to be polished at the end.

More complex shapes: Traditional processes such as casting and drilling have reached their limit
With 3D printing processes, shapes can be produced that would be impossible using any other production process. Someday it may be possible to print turbine blades with delicate internal air ducts. This would improve blade cooling, which would not only permit higher temperatures in the combustion chamber but also increase efficiency.

From square to round – More freedom in product design
This short pipe section connects two parts of a gas turbine. The fluid transition from round to square is difficult to achieve using conventional production methods. But with 3D printing, it’s easy.

Shower of sparks: Lasers fuse metal powder
The laser beam hits the bed of metal powder, releasing high energy in the form of heat and melting the metal, layer by layer. The metal then cools relatively quickly into a solid shape. If hot, liquid metal were poured into a mold, it would take longer to fully solidify and cool. This is somewhat of an advantage of conventional production methods, because slow cooling increases ductility. Researchers at Siemens CT are now working on processing techniques that would also endow printed objects with extremely high ductility – a requirement if turbine blades are ever to be printed.

We’ve come a long way since Gutenberg: Olaf Rehme analyzes a CAD model for his next printed object
When book printing was in its infancy, all printers were highly respected specialists and craftsmen. The same can now be said of 3D printing experts. Although 3D printers are already available for home use, most are suitable only for producing plastic parts. Standard devices for printing metals can already generate many shapes. But when products must withstand extreme stresses, experienced material researchers like Rehme are required to perfect the raw materials and process.

Furnace cleaner: When the printer is finished, large quantities of metal powder are left behind – and must be carefully removed
Metal powder covers the floor of the printer. The laser beam moves across the bed of metal dust and generates an initial layer of the three-dimensional object. Another layer of metal powder is then spread evenly over the object’s surface. Now the laser can print a second layer. Step by step, a complex shape is created. At the end of the process, a large amount of powder is left over that can be reused for the next printing cycle.
