    Detailed Work Instructions... Format

    We too struggle with capturing this "Tribal Knowledge". We currently use Microsoft Word with written instructions and include pictures whenever necessary. We are also preparing to possibly implement this piece of software. http://www.sequencesoftware.com/lockstep/index.htm There is a 15 day...

    Profile of a Surface on a Honeycomb Composite Core

    We had the same problem for First Article Inspection. The way we resolved it was to machine a "substitute" material to the same specifications ie. phenolic, fiberglass and measure that object to accept the fact that the machine was capable of producing the desired surface, knowing that the...

    LEAN DESIGN

    Here is another good link. www.design-for-lean.com This is a pretty good toolbox of useful ideas and tools used in "Lean Product Development". We have implemented some of these in my corporation and they work. Being in the manufacturing environment it is amazing how much waste management...

    Work Instructions, SOE's, SOP's, Build Instructions.

    Mechgunner, We have not officially used them yet, but our conversations thus far have been great. They are very friendly and helpful to talk to and they seemed to have worked with alot of different ERP/MRP systems. I would recommend giving them a call b/c I think they will do a demo. To...

    Work Instructions, SOE's, SOP's, Build Instructions.

    I have found two software companies that offer such a thing. We too have the same problem with hours lost on simple formatting things in MS Word that are nightmarish. I have recently contacted the two companies and both look promising. Feel free to look for yourself...

    Flatness relative to part thickness?

    I have a composite structure or panel that is somewhat large in size. Design engineering is trying to control the bow or warp of these parts with a flatness callout. How can I use a CMM to measure the flatness or warp of the part with respect to a surface plate? If I take points on top of the...

    How to measure composite positional tolerance?

    We currently use a CMM for inspection of finished parts relative to a single datum structure A|B|C without a problem. I thought that with the composite tolerance you have to measure not only each hole relative to datum structure, but each hole relative to each other. In other words, I would...

    Surface Profile with One datum reference - Legal?

    I am a Manufacturing Engineer struggling with the interpretation of our design group as it seems they constantly push the boundaries of what my concepts of GD&T, and interpretations are. As for the question... I have a standard panel part with a thickness. This part has several holes and a...

    How to measure composite positional tolerance?

    Thanks All, Sorry for the delay, but here is more info... The standard is the 94 - The callout does have the MMC at the Positional tolerances but not onthe datum callouts. Standard "hole" pattern callout, but my issue is that the material is composite sandwich with honeycomb. The true...

    How to measure composite positional tolerance?

    What is the best way to measure/inspect a stacked or composite positional tolerance block? For instance... .016 TP |A|B|C| and then .005 TP |A|

    Weld Stud, Titanium

    Need some help on this one? We are trying to create a weld stud on .012" thick titanium, grade 3 or 4. We have a weld stud gun but contiuously keep blowing thru the metal. Also some of our weld studs are stainless steel. Does this pose a problem with different metals? Also is cleaniness an...

    Profile of surface callout on an internal feature?

    Yes, Inspection is the problem... The machined edge lies in between the inner edge and the outer edge of the potting, thus there is a profile callout for the inner "band" of potting. In order to measure the surface, don't you have to have a surface to measure? We have considered using a mylar...

    Profile of surface callout on an internal feature?

    I have a drawing that has a profile of a surface callout for potting material that is filling honeycomb core. The potting material is an edge-fill that will be machined to net size. Anyhow the callout is for the internal edge of the the potted "track in the honeycomb" If this is in fact, not...
