Linear motion takes shape
bearings are more compact than round ballbushing bearings of the same load rating. But it is generally easier to modify a round-rail system than a square one. Round shafting can be end supported and used as a structural member in a larger assembly. And round shafts can accept diameters, flats...

NET-SHAPE metal parts in one shot
for plastic make the wax patterns. However, unlike production plastic-injection molds that are constructed of tool steel, wax molds are typically aluminum. The special wax may contain a small amount of polymer to boost structural rigidity, but it is not abrasive as are certain plastics. Injection pressures...

A fresh look at surface modeling
Solid modelers still need surface modeling to form complex surfaces. The surface model of a racing ski helmet was generated in Cadkey Workshop V21 by Louis Garneau Sports Inc., Quebec, Canada, ( ). Surfaces can be used to design structural elements which conform to the shape of aerodynamic...

Smart ways to design with Aluminum Extrusions
to have a clear knowledge of 6000 (Al-Mg-Si) Series alloys, mostly 6061 and 6063. Alloy 6061 is often referred to as the "plain carbon steel of aluminum" the workhorse standard for structural parts. And though other alloys fit the bill for special needs, 6061 is one of the most cost effective...

MICRO:Top 30 (November/December 2001)
The fully automated Expida dual-beam structural diagnostics tool performs in-fab characterization and analysis of process excursions and defects. The instrument can be reconfigured from 200- to 300-mm wafer manufacturing with minimal interruption. The tool allows users to cut, view, measure...

Software gets a grip on costs
proactive cost control. That same bracket, for example, would have one shape for a given structural load if it were made of aluminum and another shape if it were made from cast iron. FBCA provides should-cost estimates for these alternative designs, "on the fly." The conventional method for getting...

Advanced adhesives foster hybrid structures
in the automotive industry is the increasing use of metal/plastic hybrid structures. They incorporate metal-reinforcing members strategically attached to a plastic framework, combining the structural integrity of metal with the net shape and weight-to-stiffness advantages of fiberfilled plastics. The resulting...
