Not an aging rock star, "rod creep" is a fault in a fly-fishing cast where the rod rotates forward at the end of the back cast instead of stopping. Now, thanks to MEMs technology and Noel Perkins, mechanical engineering professor at the University of Michigan, anglers may have an easier time diagnosing such faults. Perkins wanted to master fly fishing and had previous experience simulating sensor-equipped submarine detection cables for the Navy. Modeling the fly line was similar, but Perkins needed devices to help understand how much his cast deviated from ideal. Using MEMs motion sensors, he built a device to measure fly-rod motion and wired it to his Palm Pilot attached to the rod. His "casting signature" can be compared to an expert's. He is looking for partners to develop the technology. www.engin.umich.edu
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
Stratasys will be exhibiting two groundbreaking large-scale additive manufacturing technologies, as well as other new products, next month at the International Manufacturing Technology Show (IMTS) in Chicago.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
