Trying to learn to thread on a CNC Lathe with a M70 controller, which is pretty similar to Fanuc as far as I understand. I'm trying to figure out how a G76 doesn't essentially smack into whatever is beyond the thread. An example part, 1" long, .5" diameter and on the front is a 4-40 thread that is .25" long. Just to make sure I'm getting the point down, the diameter could be 6", while the others are the same. I read that if the thread calls for .25" you could make it .249" and it would be less risky or something. I know that the tooth of the single point insert is not what the program would go by, but the face/front of the insert that it was taught off of.
I was trying to talk to a co-worker and started 2nd guessing what I've found. If I remember right, the lathes I've watched thread take off at a 45deg angle in +X -Z (towards chuck) and then go back to Z0. Does this sound correct?
Hopefully someone could break this down for me.
Thanks,
