Not to point out the obvious, but everything here is opinion. So basically, it's whatever your customer requires at this point. Know your customer..... Maybe someone will talk to the AS9100 and ISO folks for them to provide guidence in their next revision of the FAI specs.

Nope. Never found anything -- only a bunch of opinions. So, the way I'm working it is that recording measurements to the basics is best practice. However, until I find a spec or formal industry wide guidence....it aint a requirement.

thanks. I do have those, but I was looking for something more practical. something that summarizes and takes all the stats graphs and calcs, and puts it into application.

Does anyone know of a good, practical reference for sampling plans and AQL based inspection plans? I'm thinking an AQL for dummies, or the Mechanical Engineering's "Shigley" analog for inspection? Thanks

Does anyone know of a specification, standard, or industry best practice reference that addresses basic dimensions in first article inspections? I've checked AS9102 and haven't found any guidence. The question is whether the basic dimension must be referenced in the FAI (First Article...

That's a good site. I found that one already -- good historical and trends. thanks.

Does anyone have a good website to get current, historical, and trending for prices of Germanium and Silicon?

Does anyone know of a good specification (ASTM, AMS, MIL, etc.) for bright annealing? It is specifically for Iron Nickel alloys, but a generic spec and/or other metal would be acceptable. Thanks!

Basically terrestrial MILSPEC temps plus some -- say -70-150C. I'll check the handbook. thx.

Does anyone have any data, or even general references on the outgassing of said oxides? There's plenty out there for the stability of iron oxide on iron and CRES, but nothing on the oxides I mention.

Strong -- guess I should have worded my original question differently. I'm a green-as-can-be rookie at this noise stuff. my problem is that a system comprised of a simple "mechanism" swinging a "beam" against another material is "too loud." I'm not looking for specific solutions, just where...

Are you sure the sound is coming from the beam and not the rubber it is contacting? No. It could also be coming from the mechanism moving the beam. Can you put some duct tape on the beam to see if it helps (by providing damping to the beam mode if there is one). Been done -- not sure of the...

that's a good question, sms. But, the underlying science should be the same no? It's on the order of an inch w/ a .010 Xsection or so.

immerse the whole thing in liquid? That's kinda like the suggestion to fill my electronics box w/ sand to dampen vibrations in high shock....sorry....no liquid. I can't reveal the application unfortunately, or you'd understand some of my points.

I am making a part out of Moly 361. Does anyone know a rough estimate at the minimum cross-section you can machine with this stuff (bought bulk, going to machine it down). Are there any issues with cracking at thin Xsections (obviously at some point there is)? At what thickness? No choice...

which mode of the beam is causing most of the objectionable noise? Not exactly sure -- looking into that now via FEA (it's really not a beam, but conceptually, for this discussion, it is.) what is its radiation efficiency? Don't know -- what is this, or where can I read up? why not put...

I am trying to make a very simple system quiet - in essence, a simple thin-cross section beam banging the thin edge into piece of soft rubber. Can't change the rubber. Looking at natural frequencies, etc. of the beam. Looking at the peaks in the acoustic measurements. Any resources online...

Thanks! Great link. Not sure if I found exactly what I need (since I'm looking for solid-state diffusion, and that reference cites liquid Mn-Au), but I loved the site nonetheless. I'll look into it, and will surely use it again. Thx again.
