Good day,
Has anyone here got experience with O-ring boss porting using Inconel 718? Job coming up is going to require a bunch of SAE ports in this lovely material and was wondering what your thoughts are. My only experience using form ports is exactly zero. I assume a carbide tipped SAE form will cut the inco just fine but at an extremely slow speed. Use like a reamer, predrill, circle mill, port, thread mill. Job done. Except I assume tool wear will be a factor here. The holes themselves are pretty small, 7/16-20 SAE, 1/2-20 SAE, 5/16-24SAE.
How critical is the thread gaging for an SAE port? Are go/no-go gages the way to go here?
These are near-net complex forms that I would really like to not screw off on because they are expensive and have long lead times.
Thanks
