Steel is not about to disappear anytime soon as the dominant material used in the home appliance industry. Unlike automakers, which are turning to aluminum, carbon-fiber composites, magnesium, plastic and other lightweight materials, steel still rules in the world of refrigerators, dishwashers and dryers.

Manufacturing engineers have two options for obtaining an automated assembly system. They can get each component—an automatic screwdriver, a rotary indexing dial, a gripper—from individual suppliers and integrate the parts themselves. Or, they can ask one supplier to deliver a turnkey machine.
PHILADELPHIA—Naval Sea Systems Command has completed a fleetwide fastener study, identifying and recommending the removal of thousands of fasteners from the Navy supply system. The review identified 108,000 dormant fasteners—fasteners with no contract, requisition or maintenance history in the past five years—and 3,200 duplicate fasteners where two or more identical fasteners had different stock numbers.
Independence, OH—The Industrial Fasteners Institute has published two new reference books on fastening: Mechanical Fastening and Joining, by Bengt Blendulf, and Torque Book for Fasteners, by Joe Greenslade.
On May 22, 2012, after eight years of preparation, Space Exploration Technologies (better known as SpaceX) launched the Dragon spacecraft atop a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida. The spacecraft traveled more than 200 miles to reach its destination: the International Space Station (ISS).

Robotic screwdriving offers numerous advantages to manufacturers, such as flexibility and repeatability. However, it’s easy to underestimate the requirements of automation. Sometimes, engineers specify the wrong type of robot or overlook parts feeding issues.
Several issues need to be addressed before there will be more widespread use of robotic screwdriving. Cost, robot design, training, culture and other factors must be considered by manufacturing engineers.
