    Inspection Software

    Does anyone know of comprehensive inspection software that would incorporate items such as gauge numbers, inspection results, jobs run, etc? I'm trying to modernize my company from having a bunch of separate manual systems into one that is more global. Thank you!

    Broken diameter dimension

    I'm having a discussion with a colleague regarding how to dimension a diameter that is broken into multiple segments. Imagine a cylinder that has slots machined down its length. Is it necessary to number the quantity of segments or is one diameter callout acceptable? i.e. do we need 3X Ø1.650 or...

    Titanium Heat Treat / Aging

    We have a part that has a specific callout on the drawing regarding the processes applied to a Titanium 6-2-4-2 part. We callout that the stock must be processed to meet AMS-H-81200 Heat Treat Table 1 and then Aged per Table 3. Table 1 says to take the material to around 1600°F and air cool...

    Units in a feature control frame?

    Our head of drafting is saying that it's not acceptable to put units in a feature control frame, i.e. we have some tolerances where the number would be listed as .000005 and we'd like to put 5μin instead. I think that the standard doesn't outlaw it, so it should be fine to use the 5μin. Who is...

    Maraging C300 Heat Treat

    I have a question regarding Maraging C300 (Vasco C300, etc.). We have been heat treating this in-house for years and years and the pieces look terrible. They can develop scale sometimes, and just generally look bad, sometimes leading to scrap and other times needing to be "polished" or cleaned...

    "G" symbol on older print?

    We have a drawing here from the mid 80's that doesn't reference any standards. On the drawing is a symbol I haven't seen before. The symbol is the letter G inside a triangle and it is applied to a couple of dimensions. The best guess I have is that they mean that the feature the dimension...

    Perpendicularity to a thread?

    We have a few parts here that have what I feel is a questionable callout of perpendicularity of a surface with respect to a thread. The thread is normally called out as the datum and a counterbore below the thread has the perpendicularity callout. They are about to change the part in question to...

    Oasis inspection system

    Was wondering if anyone here has had any experience with the Oasis system. I had one here for a week running an evaluation and the Gage R&R reports seem to point to it being capable above tolerances of ±.001 with a P/Tol. ratio of about .14. At tolerances of ±.0005 the Gage R&R returned a P/Tol...

    Feature supression in drawings

    Is it possible to supress features on a part for or in one specific drawing? For example: Think of a two piece mold that you want to make separate drawings for. First the plain blocks with screw holes so they can be bolted together, then a "assembly" drawing with the cavity. Obviously if you...

    Wire EDM machine recommendations

    Howdy all, We're looking into getting a replacement for one of our existing wire EDM's and I need to do a little research on the competitors. We're looking at getting a Sodick AG400L, so I need comparable machines. We very rarely do 4th axis cuts, we mostly use the wire EDM to cut shapes...

    Close tolerance drilling of quartz with diamond core drills.

    Hello all, The company I work for is having some issues with drilling through a couple of types of materials we deal with. One is Quartz and the other is a fused silica that is made in house. The parts that need to be made look very much like thick washers. An sample part might have an OD of...
