Two Formula machines have been in service at Lockheed Martin Fort Worth for a turnkey solution milling the F-35 fighter jet center section fuselage. That project employed both the thermal management system mentioned above for the XS, in addition to an automated cell with temp control and air filtering.
“The XS machine is an overhead gantry machine that has the ability to encapsulate the entire machine without putting it into a controlled environment, including column sides, the bridge which is the cross rail, the ram and ram saddle with the exception of the guideways of the ram [the vertical axis],” said Tom Hagey, operations manager. “The ram protrudes down to the table of the machine with the head. Boxways that are hardened and ground and exposed in ambient tempera- tures are gundrilled out and refrigerated coolant is passed through,” said Hagey.
“Balanced tooling produces excellent surface finishes, extends tool life, and
prevents possible damage to the spindle.”
“AIP Aerospace Tooling Group has or- dered four of our machines, one for their Odyssey division in Michigan; the other three for their Coast Composites Irvine, CA facility. They’ll be used to produce the tools for building composite parts for the Boeing 787 and Airbus A350. One of the machines, a dual gantry model has travel of 59 × 15' [18 × 4.5 m],” said Hagey.
Tool Selection Leads to Predictability According to Ed Mulvey, technical support applications engineer, Horn USA (Franklin, TN), multitasking machining using tools like Horn’s spline milling and gear milling tools can complete a gear or

CUT THE CABLES
Here's an ingenious value proposition: use the innovative i-Wave wireless bore gage and hands-free Merlin Mobile data computer— both with Bluetooth® wireless technology—for total portability to take measurements when and
where you need them throughout the plant, then upload the measurement data to your secure quality
network.Plus you can rapidly interchange an assortment of nosepiece sizes and
styles, even ones already in your plant. Eliminating cables enables your operators to work smarter and faster. That’s another reason why innovation is part of every cost-competitive gaging solution we deliver.
