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.

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...

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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
What kind of finish would this leave with so little material?
Also, could you use a continuous seam resistance weld or how about a laser for titanium. Again, surface finish is critical.
Thanks for the info...I will be sure to read thru it. To answer your question, no I have no experience, we are actually looking for someone with this capability. Our procurement guys ahve had a little trouble so I was looking for info just to see how easily it's done.
Correct me if I'm wrong...
Hi all,
Just looking for solutions to welding .014" thin sheets of titanium, (grade 2 or 3). Is this possible? What are the methods ie. laser, adhesive etc...?
Our problem stems from the fact that we cannot purchase .014" titanium at the desired widths of 36" or greater...so we are looking...
More detail...
The honeycomb is being fabricated as a sandwich with inserts for drilling. The drilling of the 2 "datum Holes" are for post fixturing on a fixture plate for CNC routing. The drawing is for the build of the sandwich with 2 holes drilled after cure for location purposes.
The...
Thanks,
I thought so, but when addressed the design group claimed that the pattern itself is "floating", but...
doesn't that contradict the purpose of positional requirements?
Also, 2 of these locations are for an insert with a drilled hole. They did the same for these 2 holes, TP relative...
