Help needed for lathe toolpath

[LukeR054]

I need to find a correct toolpath that will allow me to have the c axis rotate whilst having a varying z axis move to mill an angle onto a part but say have an endmill only come down roughly halfway as I don't have any long enough to do it in full depths. I'm unsure what machining strategy to use if it's even possible. Any help is greatly appreciated, thanks

I suggest using a 2D Contour with wrap tool path. Attached is a quick example of how to do it. You will have to split the face and then select both sides as separate contours, other wise it doesn't know how to "unwrap" a full loop. If that doesn't make sense don't worry about it, just follow the example. Let me know if that works or if you have other questions.

Sorry I forgot the file. Here it is.

Hey david, thanks for the swift reply, I couldn't get the chain to split, i've uploaded my f3d

Ok, so the easiest way to do this is, in the Split Face dialogue box, set the Split Type to Split With Surface and then select the YZ plane as the Splitting Tool. 

Does this make sense?

Okay I got it, but i seem to be getting a layer on the left after simulation, any ideas? Do you know if i can maybe move the endmill depth further down?

[da_fish]

Yes, you can easily move the endmill down by putting a negative offset in the Bottom Height Offset in the Heights tab.

Worked perfectly just what I needed, thank you very much for your help
