When working on the ATF Advance Tactical Fighter F-22 we researched self shielding. So the number is 18 twists per foot. However the gauge does not have to get to be very small before the wire is too and stiff to twist. Shielding was very important to this stealth aircraft. My mentor researched wire impedance. The theory was developed and proven in the 1930 - 1940. What are the components of wire — cable impedance?
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
