Anyone used Langmuirs thread mills yet? Am wondering about a starting point with speeds and feeds in aluminum.

If you measure the neck diameter (thinest part of thread mill) and find the feeds and speeds for that size endmill. That should probably be a more aggressive setting depending on your depth of cut.
I thread mill everything at 15 ipm. I’ve threadmilled every material you can think of on this machine, 15ipm works well.

how much engagment
Aluminum I’ll engage .025 per pass. Steel I usually will do .015 or .020.

@langmuir-daniel @langmuir-mike : Can you guys add these information to the feeds and speed table you published previously? That would be very useful for future reference instead of digging into the forum 
Thanks in advance guys.

Thank you guys
@langmuir-daniel Is there any guidance on S&F for standard/full profile threadmills (IOW - not single profile)? I have a few but I’ve been I’ve been afraid I would chatter them to death.
I don’t use them because unless you’re running substantial production- being locked into one pitch is really disadvantageous. If you got them run them. Chatter likely won’t be an issue. No different than a rougher with high axial engagement.
