Is this a turning profile bug?

[dca911t]

So I wanted to turn this part on the lathe.

I wonder if this is a bug because if the yellow plane (X axis) is
not intersecting the profile, it will not generate a valid tool path.
I suppressed some of the features to get back to where the yellow
plane (X axis) IS intersecting the profile and it generates the tool path.

I would think you should be able to select the faces of the profile
and still generate a tool path even if the yellow plane (X axis) is
not intersecting the profile.

Turn on Spun Profile (I believe its's in the Setup).

Thank you very much, that fixed it!

Do you know what "Spin Profile" is actually doing?

Thank You

I believe it looks at the outermost profile around the entire model along the specified (X) axis and rotates it around the Z axis.

Also please mark my answer as a solution so others can see the issue has been resolved (if it has, that is).

So to me it is Abby Normal to have to select "Spin Profile" in "setup", when you are working in a "Turning Profile".

You should be able to just select a face and generate tool paths based on the face selected.

Is "Spin Profile" good workaround? Yes, But is it the best solution??

Thank you atomkinder67, for your prompt, answer, it allowed me to move forward!

Well this is how HSM does it, at least for now. Keep in mind that it retains its 3-axis system in turning as well, so mill-turn is an option and if one has 4th axis capability you could run this with an end mill even in a turning center if it has live tooling. Spun Profile makes a "turnable" cylindrical profile even with "broken" geometry.

And yes, other CAM systems do this differently, but it is what it is.
