Helical flute cuts

[TheKid09]

hey all,
Ive been trying to figure out how to cut 3 flute cuts with an .070" E.Mill down a part. It needs to Start at 0deg and go .500" in length and wrap around the part 130deg from zero.

I know how to index it, but i am not sure on what codes to use to make it create the helical flute cuts down the part...

this will be done on an L20 Citizen..

any ideas?

Thanks!!

insert your milling prep code here
G28H0
G0 Z0 position cutter
G1 X.5 PLUNGE CUTTER TO DESIRED DEPTH
G1 Z.5 H130. F390.(1.5 IPM IN DEG PER MINUTE)
G0 X1.0 CLEAR THE PART
Z0 C120.
G1 X.5
G1 Z.5 H130.
G0 X1.0
Z0 C240.
...... AND SO ON
im not sure how the milling works on a citizen but i have used code similar
to this on a tsugami before

I had ran across the incremental rotation, I just wasnt sure how to calculate the proper feed rate. So, I wasn't sure if it could be done....

Thx!! I do very much appreciate the help on that... ill try it tomorrow.
