    Bill of Materials

    When I worked in medical devices we had engineering specifications for the materials, and called that spec out on the general notes of the drawing. Is GMP still a requirement? https://www.ispe.org/initiatives/regulatory-resources/gmp "Art without engineering is dreaming; Engineering without...

    Copper Projectile - Raw Material

    BiPolarMoment, no, this was from an article about Franklin Armory and their new Reformation Rifle, having straight rifling and shooting "footballs". A copperclad round here would be very inaccurate I think. "Art without engineering is dreaming; Engineering without art is calculating." Have you...

    3D Printing note

    I'd called out "FDM PRINTED" instead of an actual 3D printer brand, and maybe add your requirements for layer thickness. If you don't want your parts bonded together, add "NO SEAMS" or similar wording. "Art without engineering is dreaming; Engineering without art is calculating." Have you read...

    Wheel Between Two Plates

    What load, what speeds? One plate could have a D-hole. Shaft would have corresponding flat on one end, then grooves in the shaft for c-clips or e-clips inside the plates to prevent axial movement. Could complicate further by coining recesses in the plates so the ends of the shaft are flush with...

    Worst job interview answers

    I once interviewed a candidate, we were looking for an engineer that was good with linear motion and controls. His resume indicated he designed a laser marking system with +/-.002" positional repeatability. When I asked him to describe his device he started using sounds effects. "The laser...

    Do you work in an "Open Office Space"?

    "More collaboration" in open-office speak simply means people can gopher over the low wall, ask you a question they were too lazy to research, and plop down and continue watching (insert any interests) videos on their cell phone. At least that has been my experience. "Art without engineering is...

    Painting Quality Acceptance Standards?

    Thanks for that search link IRstuff, I had it years ago, then lost it. One of those out of sight, out of mind things. This product is indoors, locked away in a closet or server room, in the dark. "Art without engineering is dreaming; Engineering without art is calculating." Have you read...

    Painting Quality Acceptance Standards?

    The SECC is washed and oven dried, but there is no primer. The application looks decent, there was just a request for some standard on the drawings to allow for rejection of light/heavy application, orange peeling, etc. I have seen some PDFs online defining Class A/B/C surfaces (automotive...

    Ooey Gooey Rubber Feet

    This has happened to one (out of four) step pad on my 4yr old F-150 running boards. The peculiar thing is the pad that has deteriorated is in the least used position, rear passenger, driver side. "Art without engineering is dreaming; Engineering without art is calculating." Have you read...

    Painting Quality Acceptance Standards?

    We are having some items manufactured in Asia, and the paint quality of the final product has issues from application to shipping. We've sorted out the shipping and packaging issues, but a VP would like us to: "add standard reference or class call-out for the paint quality such as Class I, II...

    Form, Fit, or Function

    If a part is not backwards compatible, then it is considered a new part and should get a new part number. You are correct too, if FFF changes it should always be revised. The caveat is that some FFF changes should require a new part number as well. I also think it matters if you are building...

    Solidworks in kitchen design

    I would use a "master sketch" and save each one as a different files instead of using Configs, especially if you have multiple users. "Art without engineering is dreaming; Engineering without art is calculating." Have you read faq731-376 to make the best use of these Forums?
