Hi all........

Recently I decided to attempt to produce a couple of
internally
splined couplings out of steel. Dim's a length 3 inches,
od 1.750,
id to fit 1.250 od 14 spline 25 deg p.a.male spline! Somehow
I managed
to make indexing tooling and using a pair of custom ground
broaches
I was able to do it but sure learned a lot on the use of
broaches!
So my question is, how would this part be done in a
production
situation? Most surely not the way I did it, one spline at a
time with
_many_ passes each! I don't see how a cut that big can be
done in
one pass through a three inch tube, that's a big chip to
handle.
Ideas?
