Calculating ball screw load-life? Don't forget preload.
Features 1/27/2004 Post a comment Can a ball screw with a reasonable amount of preload but no outside thrust last forever? Eschatological considerations aside, it's not likely. The balls still have to resist the internal, preload force.
Flexible and rigid plastics join forces-inside a blow mold
Features 1/20/2004 Post a comment Hybrid injection molding technology, which joins metal and plastic inside the mold to produce structural components that offer the best of both materials, has been around for more than a dozen years now. But Bayer Polymers, a pioneer in this technology, has now come up with a brand new kind of hybrid based on extrusion blow molding.

More 'Power' for the Parking Project
Features 1/6/2004 Post a comment How do you deal with a CAD model that has 500,000 components, and when you open the file it consumes 3.7G bytes of memory? Beefing up your computing power to a 64-bit workstation is one solution, as engineers at EPAQ CARE Solutions learned when they designed an 11-story, 470 bay, fully automated parking garage.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
