    basic dimensions and first article inspection

    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.

    basic dimensions and first article inspection

    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.

    Sampling Plans and AQL

    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.

    Sampling Plans and AQL

    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

    Reporting GD&T data on First Article Reports

    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...

    Commidity pricing on Si and Ge

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

    Commidity pricing on Si and Ge

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

    Bright Annealing Spec -- is there one out there?

    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!

    Outgassing of Silver Oxide, Copper Oxide, or Cusil in Vacuum

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

    Outgassing of Silver Oxide, Copper Oxide, or Cusil in Vacuum

    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.

    Need to make a simple mechanical system quiet

    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...

    Need to make a simple mechanical system quiet

    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...

    Need to make a simple mechanical system quiet

    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.
