The project’s goal is to develop advanced machine tool technology that would allow inspection of parts during the manufacturing process while they are being shaped by machinery, said Gary Conley, president of TechSolve. If the part is not being made according to specifications, a computer would be able to make production changes to correct the problem.

So the procedure is to build the aircraft, then test the design, then develop the manufacturing technology?

No, it's called Quality Assurance. The procedure is just being automated and integrated into production.

Seriously, did you read the article and comprehend it?

The manufacturing process will not change the design, it's testing the output of the process for accuracy, automatically.

With this you won't have to wait until the machine is done with the whole part, to have a different machine make measurements to inspect the part afterwards. This will allow the machine to make corrections on the fly or report discrepancies for human intervention before untold numbers of 'bad' parts make their way into an aircraft.

Think of a cutting bit being work 0.001", and the very first part the machine makes is 0.002" too large. The machine would be able to compensate, make the corrections for the bit wear, and continue making the part with the 'revised' cutting scheme.

Now I'm not saying this is exactly how this particular technology works, but think of the time that could be saved on a 2 day machining operation that can be inspected while it's in work, and not waiting 2 days for completion and another day for inspection, meanwhile more parts are being made that will require rework or scrap.

This new technology could also use some sort of 'on the fly' NDI process where sound, electric current etc is used to check parts for voids, inclusions, what have you...

There was issues years ago in turbine blades where master molds were being worn due to overuse. The non-conforming molds resulted in non-conforming casts, that resulted in non-conforming castings, which resulted in non-conforming blades, which after time, use, heat, stress, etc.... would cause a Viper to crash. Thousands on thousands of blades were affected and required replacement... If this type of technology would have been available, the first blades that were non-conforming could have been found at some early point in the process (not before Vipers started dropping from the sky) and aircraft (and many more engines) could have been saved.

Don't get me wrong here Cobb, I enjoy a lively forum/debate, but how old are you? Widen your gaze at some of these articles and posts before you troll yourself away.

"The technology is intended to build on advanced processes some manufacturers already use. It would be useable for both composite and metal parts, Conley said."

Cobb,

Did it ever occur to you that manufacturing processes are evolutionary in nature? If this stuff is made to work, then it could mean significant cost savings down the road. Industry is always trying to find a better, more efficient, less expensive way to make a product. Is this news to you?

Quality assurance/control in realtime.. cool, specially if you intend to build in quantity.

You know what's the funny thing TEG, technically he's sorta right... I mean he's got two of the three parts of the processes for the GAO's best practices:

Complete underlying technologies development -> Complete Airframe development -> Complete manufacturing development.

Don't worry TEG I know what you're saying and he wouldn't get what I'm talking about regardless.

It's called quality by design, and it's been around for awhile. The problem is that you cannot integrate software into it until the parts are made, and have a statistical overview of how they come out. It will be more than fine for this assembly line.

For the F-35 you can expect new manufactering techniques and technologies to be introduced as they come available. This is just first of many.

That's an given. And that's not what the GAO best practices is talking about anyways, which is the development cycle. I found it humorous that Hcobb actually kinda said something correct, in a completely misleading post.

@Hbpencil......Well just like a good man can occasionally fall into bad the bad man can occasionally fall into good.
