Drilling stack materials
The aircraft industry now has the means to precisely machine multilayer material combinations. These combinations, called stack materials, include several thin layers of different materials. Aircraft skin, for example, could consist of titanium, aluminum and composite layers, according to Lee Coleman, automation division manager for Suhner Manufacturing Inc., Rome, Ga.

Smarter by design
I'm not a huge fan of machinist's vises. Even with a speed handle and a couple cups of coffee in your belly, it seems like it takes forever to crank them open wide enough to change a pair of jaws. And once they're bolted in place, having to tap them in with a hammer and check them with a dial indicator only adds insult to injury. Surely there's a smarter way to hold parts in a machining center.

Providing help for engineers
The majority of engineers I've worked with are solution seekers who usually go out of their way to make things easier for people working on their projects. However, as a result of the physical separation of engineering departments from machine shops, communication and feedback often suffer. Machinists who provide feedback to engineers help both groups work together more productively, and engineers would do well to spend time talking with shop personnel to determine what obstacles they face.

ITAMCO pushes the innovation envelope
It's fitting that "Technology" is part of Indiana Technology and Manufacturing Cos.'s name. In addition to providing a full slate of machining and assembly services, ITAMCO created what it says is the first industrial Bluetooth transmitter (called iBlue) and continues to develop a broad range of manufacturing apps for mobile devices and Google Glass. What's more, ITAMCO has produced a virtual manufacturing showroom and developed a manufacturing forklift simulator that allows users to interact with factory equipment using the MTConnect protocol, Autodesk Factory Suite, Unity 3D game development platform, Oculus Rift virtual-reality headset and Leap motion controller.

Remembering a teacher
I was saddened to hear about the passing of David A. Dornfeld, professor of mechanical engineering at the University of California, Berkeley, who died of a heart attack on March 27 at age 66. Although I never met him, I considered him to have a brilliant mind and be a great editorial source—someone who returned my phone calls and had something intelligent to say.

Lead Angle: Invaluable resources
Early in my stint here, I called Alan Baker, founder of toolmaker A.B. Tools Inc., in connection with an article I was writing about thread milling small-diameter holes. I started the interview with a general question about available thread mills sizes for these applications and was encouraged to first gather that information from Machinery's Handbook and then call him back. I thanked him before ending the call and turning to the appropriate section of "The Bible of the Mechanical Industries," published by Industrial Press Inc.

Moving large, complex parts calls for specialized equipment
Until I started working for Mitsubishi Hitachi Power Systems Americas, lifting parts was never a consideration in daily production. Previously, the parts I dealt with were small, usually never larger than a dinner plate. Lifting equipment, such as forklifts and pallet jacks, were often employed, but only to move raw materials to a machine tool or to load and unload trucks—never as part of the production process.

The contours of a robotic 3D-printing platform
Arevo Labs hopes its new RAMP leads to better 3D-printed componets for the defense and aerospace industries. Arevo touts RAMP (Robot-based Additive Manufacturing Platform) as the first system of its kind optimized for 3D printing of composite thermoplastic parts. The system includes a 6-axis robot arm and end-effector hardware for deposition. RAMP can accommodate build envelopes from 1,000 cu. mm to 8 cu. m, depending on the size of the robot used. The end effector consists of a deposition head with special thermal management technology for processing carbon-fiber-reinforced thermoplastics.

Growing demand for microparts challenges suppliers, users
Ever machined parts so small that they not only fit on a penny but can sit on old Abe's nose? Cutting parts and part features in this Tom Thumb world often comes with Titanic-sized challenges, such as unexpected cutting tool breakage, deburring parts the size of typical burrs and machine tool spindles speeds that come up short. Sometimes just handling ultrasmall parts is a gargantuan task.
