Spline Gages ???? What?

cheesiechanman
Good Morning ladies and gents,

For those of you who have ordered Go/Nogo gages for splines... how do you confirm they are made correctly? Do you all have any information you can pass along to help me understand how to compare customer print with gage maker go/nogo print? I don't know a whole lot about spline gages or splines in general and would like to understand them a little better. I attached the part print for the spline of the part. Now how would i take this and determine the sizes/specs of a Involute spline go and nogo gage.ConfusedConfusedConfused

Thanks in advance

  • The issue is that from PPAP to now the go gage has stopped fitting into the parts. So the QM is saying they are made wrong. And I don't have the knowledge to say one way or another. Comparing the manufacturer print to the customer print tells me nothing.

    When we had these made the guy (here at my job) that ordered them sent the gage manufacturer the part print and said "You are the experts. Send us a gage for this." Now I'm left to figure out if they are in-fact experts and made it correctly. So I have to prove that they are good and to spec... and the QM has no grounds that they are bad or out of spec other than they dont fit current production.

    I would do as said (sort-of), see if the manufacturer is an accredited facility and find the COC. If they suspect the gauge is bad, I'd send it back to be checked and recertified. I would also ask the machinist if they changed tools at all cause the offsets may need to be adjusted although this may be a moot point if the splines were cut with an EDM.

    To summarize, attack it from both angles. Have the gage checked and talk to the machinist.
