cutting a radius

i'm trying to cut a radius on the front of a part. it looks like a tit on the front.
G1X-.015
G3X.0458Z.015R.025
G1X.114
X.196Z.056
I'm using tool noise comp but when i add the g41 it does even go anywhere close to the part. i'm using a .007 rad insert.

Thats all of the block that i can remember. i'm at home now. i made the post while at work. i know i have to use the G41 but when i but it in i get an alarm. it tells me that it cant complete the block but alarm book doesnt give me a fix. just tells me to edit the program. the only thing i can tell you now is that its got a .025 radius on the center of the face then it should radius into the face of the part then face up to .114 dia. then cut an angle at a 45 degree to a dia. of .196 which is past my .193 dim that is my thread major.

one other thing that i might have wrong. the direction that tool is pointing in the geometery page. the book indicates that it should be pointing to the 4 but the guy that programmed the machines before me had it as a 3 which in the book it shows 3 to be a backturn. i'm using a 35 degree front turn with a .007 radius. i dont know if this helps but it still dont work.

???

What size Radius are you trying to cut? And I take it the front of the part is not your Z0.? Your best bet is to program not using cutter comp it sucks on lathes....

cinomarra is correct. You need g42.

Are you using a sub spindle?
Because it's rare that i see a lathe that is Z positive towards the chuck unless it's a sub chuck.
If your trying to go CCW then your gonna go the long way around.
