Hi, I have a clausing CNC lathe with the fagor 8055 controller. I have to make some 2-3/8 internal flush joint threads (oilfield) everything works ok but on threading cycle on this controller i cant enter Taper Per Foot, i must enter degrees. Does anyone out there know how to enter degrees,minutes,seconds into this controller? what format or how do you enter it? Also when threading, someone told me that there is one of the values that must be entered in a negative number, is this true?

Any help would be greatly appreciated as i am not very educated in the CNC world

Thanks, Clay
