use a pipe tap.

Sorry can not use a pipe tap on a titanium aircraft part. If anyone is able to write up the canned cycle or just the G76 line to incorporate the angle I would be greatly appericiative.

Below is an example of a 4 TPI thread with a 3 inch taper per foot.
The “I” value is calculated by the radial amount from the target point to the finished diameter.
On an OD thread this will usually be a negative value. On an ID thread this will usually be a positive value.
In this case we start at Z.5
TPF = 3.0 Length of thread in program =3.97
TPF/2 = 1.5 Length of thread + dist to start posit = 4.47
Solve for I
12(I) = 4.47(1.5)
12(I) = 6.705
I = 6.705/12
I = .55875
I = .559
