Stainless steel products that require both cold heading and machining operations have been notoriously troublesome—because stainless alloys that machine easily don't lend themselves to cold forming and vice versa. Carpenter Technology Corp. (www.cartech.com) recently developed an alloy intended to support cold forming and various machining operations, including drilling, slotting, and broaching. Called 302HQ-FM® stainless (S30431), this stainless grade offers a low work hardening rate to foster cold forming operations. At the same time, it has a machinability rating approaching that of Type 303 stainless.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicle’s parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but that’s just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
