    I'd have honestly tried probably 3 passes at .006-.007 stepovers with 1 spring pass. Lowering the spindle seems to be the only thing to work for me with smaller tools in tough materials. The...

    If you did try again, i'd try slowing the SFM down a bit. Would help reduce the vibration a bit which may have lead to the failure. Id run my threadmills around 50-75 sfm for hastelloys with great...

    I made a spreadsheet to quickly convert linear feed for ID interpolation. Just punch in your sfm, threadmill dia, thread major, and desired fpt and it'll spit out a number for you.

    Camworks is a tough one to use. I've used solidcam, featurecam, currently working in mastercam. Camworks was the most annoying one to use. Has a mind of its own.

    Im guessing you're programming mazatrol. Set your chamfer interference size much larger and see if it will run. If you're chamfering a 1" hole, set it to 1.5" or something.

    On a Mori I used to run you could direct your M198 to a specific storage location by adding an "H" (I believe).

    For instance, M198 P0123...

    Bummer.

    If thats all you have to work with, try interpolating @ 75-100 SFM @ .0005-.001 IPT with 2 spring passes. I know it looks slow, but the lower SFM will not cause as much...

    If you experiment with the feeds and speeds, you can usually attain a nice finish by boring those .875 IDs. Assuming you have a nice boring head.

    For getting a nice finish in a bore, you could check out roller burnishing. I've been able to achieve 4-6 Ra finishes in 316 SS using burnishers. Not sure about 4340. You'd want to have a nice reamed...

    Clamp it lightly and DO NOT hammer it down. If you hammed it down, you will clamp it flat but it will return to its bowed state when released. Skim ~.01 .015" off one side. Flip it, now you can...
