All,
I’m trying to mill a conical helix on a HAAS mill and am getting a 304 Alarm, “Radius at start must match radius at end of arc within .001”. I’ve had this trouble in the past on a Fanuc control and was able to change a tolerance value in a parameter to stop the error. I’ve contacted HAAS and they are looking into it but haven’t been able to find anything.
My question; is anyone milling pipe threads or a conical helix on a HAAS successfully, and if so how? I’m not actually milling pipe threads so I’d rather not break this into small lines if possible.
Thanks in advance,
Dave
