I just ran into a part that I've been troubling to get it machined with NX 10.0.3.5.
Tried many scenarios to machine this, using Streamline, with 4ax Normal to Part with part geometry, 4ax Normal to Drive Axis and also Relative to Part, Drive with tilted tool angle axis. With these I tried different combinations of towards drive, away from line, tool axis projections didn't help.
What I want to achieve is to machine walls of the geometry with the side of the tool, one side pass for roughing and one side pass finishing, while extending Z level a little bit after last Z level, having smooth toolpath on corners.
Honestly, my effort didn't get me anywhere near what I want.
I'm not very experienced but I can say I like to figure things out by myself, but this time I really felt that I need help on this, can somebody point me towards a good documentation, sample file or right direction?
Solved! Go to Solution.
*surface area method, step% 0,100 -> -10,100 or something like that, ( depend on directions )
tool will go under bottom face
number of stepovers 0, Zig,
*projetion vector toward drive, back off distance 1, 2 ..try
*tool axis swarf drive,
drive method are % -10 , 90, number of stepovers 2
Try same logic with streamline drive method.
Another option could be contour profile, which is the new way of swarf drive programming.
Do you also know how to keep tool tip in the middle of cylinder so it creates more consistent moves?
You will have to use tool axis away from line to get this, but it might not create a nice tool path.

but be carefull, tool aligned with walls doesnt point to one line/axis along whole wall surface (maybe never) so in that case tool wont be aligned with walls.
definetlly use contour profile operation or swarf drive tool vector.
@dfdfgsIve tried to keep tooltip in the middle with countour profile operation with ring height parameter but I wasnt satisfied with tool paths.
