Siemens Meet at the Machine: Be productive from day one of new CNC machine delivery

Traditionally, many programming, validation, and training activities begin only after a machine is installed. Not anymore. Meet at the Machine is Siemens' new initiative uniting machine builders, software, and automation for next-level CNC through a continuous digital thread across engineering, programming, virtual validation, and execution. By pairing a Digital Twin with Digital CNC powered by SINUMERIK, manufacturers can prepare, validate, train, and optimize workflows before your specialized machine's physical delivery! TRAK Machine Tools is the launch partner -- see what they are doing.

How to master metal powder management in 3D printing

What's the real cost of "good enough" powder tracking for powder-bed fusion 3D-printing machines? According to Tim Wischeropp, CEO and Co-Founder of amsight, the technology is rife with hidden costs. Every cycle, every handling step, every exposure, and every mixing decision plays a part. Surprisingly, though, with the right strategy, users can turn their losses into a competitive edge. Learn how.

Custom 3D-printed steering wheel for jet dragster

Jet dragsters use General Electric J85 engines -- the same turbines pulled from U.S. military F5 Freedom Fighters -- mounted to a custom 26-ft chassis. The racers achieve quarter-miles in 5.5 sec, but standard metal parts can fail custom ergonomic needs. Traditional manufacturing of low-volume aluminum steering wheels demands long, 8-day lead times, high costs, and multi-piece assemblies. Larsen Motorsports solved this by replacing metal with continuous fiber 3D printing using the Markforged X7. Embedding continuous carbon fiber into an Onyx nylon matrix allowed them to target specific load paths, delivering a custom steering wheel that is stiffer, lighter, and faster to produce than aluminum.

GE9X engine for Boeing 777X aircraft features fewer, thinner composite blades

The GE9X engine for the Boeing 777X aircraft will feature fewer and thinner composite fan blades than any GE widebody engine in service. To do this, GE is designing a new composite fan blade using next-generation carbon-fiber composite material.

"It has been a decade since GE designed a new composite fan blade for the GEnx engine," says Bill Millhaem, general manager of the GE90/GE9X engine programs. "Carbon-fiber composite material has advanced in those 10 years, and the advancements enable GE engineers to design a thinner GE9X blade, which is just as strong as our current composite fan blades. Fewer, thinner blades will enhance the airflow and make for a lighter, more efficient fan that will help with the GE9X engine's overall performance and fuel burn."

The new material incorporates a higher-stiffness carbon fiber and a new epoxy resin. The leading-edge material will also be modified from titanium to a steel alloy to further enhance the blade's strength.

Last year, GE engineers received positive results from material testing on full-size GEnx blades. Testing of the new material continues this quarter in preparation for next year's testing on the new GE9X blade design.

The GE9X fan blades are the fourth-generation composite fan blade design, built on the success of the GE90-94B, GE90-115B, and GEnx engines. GE engineers continue to work the final design of the GE9X fan blade that will incorporate improved aerodynamics.

GE will spend $300 million in 2014 on technology maturation testing for the new GE9X engine. Tests include the Universal Propulsion Simulator (UPS) fan performance tests as well as testing of ceramic matrix composite components in a GEnx engine.

The GE9X engine will be in the 100,000-lb thrust class. Key features include a 133-in.-diameter composite fan case and 16 composite fan blades; a next-generation 27:1 pressure ratio 11-stage high-pressure compressor; a third-generation TAPS (twin annular pre-swirl) combustor for greater efficiency and low emissions; and ceramic matrix composite (CMC) material in the combustor and turbine. Almost 700 GE9X engines have been ordered by customers since it was launched on the Boeing 777X aircraft last year.

The first full core test is scheduled for 2015. The first engine will test in 2016 with flight testing on GE's flying testbed anticipated in 2017. Engine certification is scheduled for 2018.
