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!
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...
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...
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...
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...
Thank you, that makes sense I guess since the rev on this print is up to J. It's just odd that there's no other similar letters on the print.
Thanks again!
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...
T or F: The only reason for applying GD&T specs on component drawings is to reduce mfg costs by allowing relaxation of linear tolerances.
False - There are some features that cannot be captured by linear dimensions which GD&T can. Example: Total runout. I have no idea how I would callot out this...
unclesyd: I am familiar with those thread plugs you linked too. We actually have some of them but they are not meant for accurate inspection, but rather for gaging the particular size of a thread and they don't come in the thread designation we need.
I have thought of creating our own for the...
KNEAT: Yes, bottom of face is perp to thread.
unclesyd: The issue is setting up some way of measuring to the thread, what should be "probed" when doing so?
ewh, while I agree with this statement, I still don't know how you would control the perpendicularity of the thread to the counterbore. Yes, make the counterbore a Datum, but what to gauge on the threads?
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...
Thanks everyone for the input. As usual, not enough information in the opening statement I suppose.
The corrosion resistance is not of the highest importance, I would just like the steel to not rust the instant it sees a raindrop. The part will see normal weather, no special acids or corroding...
