Folks, the discussion here about SawStop potentially being applied to robots working with humans gave me an idea. Please check out this post about possibly starting a Design Ideas forum and tell us what you think: http://www.designnews.com/author.asp?section_id=1392&doc_id=259964
78RPM, I agree about 3D printing making stuff that's too complex to do any other way. That's definitely one of its big draws. BTW, the photo in this story doesn't show the $70 titanium part that bone grows around; that's an acetabular cup. The photo shows a titanium bone rasp for hollowing out femurs, as the caption states.
Even more than changing the production lines, that sawstop works at the expense of saw functionality. Consider that it stops the blade with a ridgid stop lever jammed into the swas teeth. So it does stop fast enough to prevent an injury , which is within one tooths distance on the blade. So the blade attachment may be damaged, and for sure the blade is sort of reshaped a bit, and that expensive stop actuator must be replaced, since the high presure charge has been used. So your saw is out of business until the expensive part is replaced. That may be OK for a home experimenor but it will be a big problem for folks using the saw for making a living. Then there is the question about what if you don't replace the driver, but instead just remove it. That means that you have defeated a safety device, and can be attacked by the OSHA man.
So while the sawstop is an interesting device, it is a big burden as well. Next question is how many folks do cut off fingers every year? Not that many, I don't think.
It's also easy to see why the power tool industry resists the technology, William K. The idea of implementing this technology raises the possibility of having to invest gigantic amounts of capital to re-tool their existing production lines.
Charles, The interesting point associated with that SawStop invention came from the scientist that I was working with at a previous job. He pointed out that nobody makes any money off of safety devices until you can get the government to force everybody to use them. Examination of the safety things that we have today does show that it is absolutely correct. So in re3ality it is seldom about safety, it is always about profit.
If everybody really wanted the safest car possible we would all be driving Volvos, but as you can see some folks consider other aspects to be more important.
And some safety features only benefit those who should be limited to driving speeds of under 20MPH, specifically the new stability control systems that we will be forced to purchase in the near future. One more reason to stick with older model cars.
Agreed, William K. There are several reasons why saw manufacturers didn't rush to adopt SawStop -- another of which is the licensing fees. I have to admit, though, the story of the SawStop inventor is an intriguing one.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
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.
