Honeycomb Heroes: Making Composites for Aerospace

There’s an old saw that if bumblebees were aeronautical engineers they would know they can’t fly. Quite apart from the miracle of their flight, bees also happen to make a lightweight structure of surprising strength, just the sort of thing you’d want if you were building aircraft: honeycomb.

Searching for the Perfect Lightweighting Recipe

Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.

3D-Printed Parts Restore Cars’ Glory

Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.

Mix and Match for Lightweight Autos

It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort.

Nano Molding and Tooling

The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.

Milling vs. Grinding for Rapid Stock Removal

A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.
