MOTION CONTROL: Helical Products Co.’s “machined” springs can provide linear deflection rates. Unlike traditional wire wound springs, virtually all residual stresses are absent. There are no internal stresses to overcome before deflection occurs, which can be the case with traditional springs. With machined springs, all coils deflect under load.
One big advantage of machined springs with two or more integral coils is that not only are there redundant elastic elements should a failure occur, but a failed element (coil) will be physically trapped by a second coil, (or multiple coils). In many cases a broken spring will continue to function.
There is no tendency for machined springs to squirm when deflected and no restraint is required to resolve the free moment. Multiple starts (coils) make loading points irrelevant on the radius of the spring and also increase parallelism accuracy. With machined springs, perpendicularity, parallelism, lateral bending, axial and torsional rates can be for all intents and purposes guaranteed.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
