Need Help!- threadmilling in surfcam

[actionman]

Hello All,
I just got a new job, and I need to threadmill a 1/8-27npt in surfcam 2004 and
on a Haas VF-4. I'm a Mastercam user and I'm unsure about the settings
in surfcam as pertaining to tapered threads when it talks about some of the diameters and such , any help would be appreciated as I am under the gun
(aren't we all) . I have a hard time finding the cut comp and so forth .
The tool I am using is a micro 100 thread mill it says .220 on it. It also has like 12 grooves (threads)

thanx
Joe

The tap must be 1/8-27 npt.
You dont need surfcam to program it.
If you are machining aluminum:
go down , go right make a regular g3 with z up.
go back to the center, go up.

If you want to do it in surfcam .
nc 2axis thread mill
select tool.
now make sure to write pitch 1/27
play with the rest of the parameters they are easy to understand.
Good lock.
