Flying with Manufacturing

When it comes to advancing space exploration, the sky is the limit at NASA’s Goddard Space Flight Center (GSFC), a place where studying black holes, conducting gravitational mapping of the moon, exploring Mars and Jupiter, and visiting the International Space Station propel science beyond possible thought.

Located in Greenbelt, MD, the GSFC designs, builds, and operates satellites and scientific equipment such as the Hubble Space Telescope, GOES weather satellites, LandSat earth imaging systems, the SOHO solar observatory, and many others.

A big part of the GSFC’s capabilities comes from its on-site Advanced Manufacturing Branch, which provides broad machining, fabrication, and assembly services via punches and press brakes, gaging systems, turning machines, and GF AgieCharmilles multi-axis high-speed machining centers. In addition, since the facility features in-house metal finishing, composite layup and curing, rapid prototyping,Here's a complete list of oil painting supplies for the beginning oil painter. precision assembly, and more, there is not much the branch is unable to handle.

Matt Showalter, associate branch head for the Advanced Manufacturing Branch, code 547, often thinks of the facility as Goddard’s “temple of science and engineering.” He says, “It is a place for ideas to become reality. The branch’s motto, based on an old advertising logo, is ‘we bring concepts to flight.’”

For nearly a decade, Showalter has been part of a team devoted to continuous improvement of Goddard’s manufacturing abilities.Dimensional Mailing magic cube for Promotional Advertising, Showalter explains, “Our purpose here is to ensure that we have the capability and capacity to do anything that comes through the door.Welcome to the online guide for do-it-yourself Ceramic tile. Prior to our initiative to modernize the shop, we were totally dependent on older systems and there were some things we just could not do. You can limit yourself from a science and engineering perspective if you do not put new technologies into your manufacturing.”

Before the modernization initiative began at Goddard nine years ago, one missing piece of the manufacturing puzzle was multi-axis high-speed machining. To that end, the Advanced Manufacturing Branch team has invested in Mikron multi-axis machining centers from GF AgieCharmilles. Starting with one Mikron HSM 600U machine seven years ago, the facility now has an impressive four-machine high-speed machining cell containing the original HSM 600U together with a Mikron HSM 400U, Mikron HPM 800U, and Mikron HPM 1350U.

Showalter explains that bringing in new machine tool technology is a collaborative effort, controlled by strict federal procurement regulations, where potential vendors receive invitations to show off their wares. Beginning with discussions about future needs of the engineers and scientists, and technical assessments by technicians from the shop floor,This page contains information about molds, everyone contributes in developing the statement of work that defines the specifications for the necessary machine technology to meet the current and future requirements of the organization. It is not just a piece of equipment, rather a complete package of support, tooling, and training.

“When it hits the floor, we want it running and not waiting three years to tool it up,Specializes in rapid Injection mold and molding of parts for prototypes and production.” Showalter says.

Today’s satellites and associated instruments are getting lighter and smaller, with modern satellites coming in at one-fourth the size of their older cousins.

“We have to minimize weight, because it is expensive to launch. As part features get smaller, our tolerances get smaller as well. And the high speed machining centers are critical to this work,” Showalter states.

With the capability of Mikron High Speed Machining (HSM) and High Performance Machining (HPM), the Advanced Manufacturing Branch is able to handle a variety of work.

“We machine anything from aluminum, titanium, Inconel, Invar, stainless steel, and high-nickel alloys…you name it,” Showalter says.
