MATERIALS: Acme Industrial Co., a subsidiary of Jergens Inc., has announced a new line of Key Locking Studs. These key locked fasteners (also known as staked studs), have a solid one-piece design to provide high pull-out strength and torque-out capabilities. They are used in original equipment, or to repair damaged threads. The studs’ keys are driven down into the threads of the surrounding base material to securely lock them into place and to provide a mechanical lock against vibration.
Acme Key Locking Studs are produced to NAS and SAE Standards (MS51833 and MS51834). They are available in a full range of inch and metric sizes, in both lightweight and heavy duty versions. The studs are available in a variety of materials, including 303, A286, 17-4PH CRES and 4140 Alloy Steel.
Key locked studs provide security and “repairability” in applications where a through-bolt / nut combination is not possible. They are superior for use in soft materials such as aluminum or magnesium. Installation is easy, using standard drills and taps. An important feature is the ability of staked studs to be removed without damage to the parent material by using a standard screw extractor.
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.
