05-24-2008, 01:27 AM
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)

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.

G17 G40 G80 G90
T1 M6
S600 M3
G0 G90 X0 Y0
G43 Z0.1 H4 M8
G1 Z-0.2 F5. (I know it can be G0 here but I am not saying it )
X0.035 f2.
G3 Z-0.163 I-0.035 J0
G1 X0
G0 Z0.1

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.
