Using Solid Models as Stock In Lathe.

[Anonymous]

Hello Fusion 360 forum,

I am new to Fusion but i'm an experienced programmer who likes to write my programs by hand. My only 3D cam experience is in ProE / Creo and mostly learned through their on-line tutorials and all of that in lathe only. I always have a customer supplied model and usually make my own stock model which I then assemble together and start making my tool paths.

So I tried the same thing in Fusion 360 and have some success and some failure with my very first try. I got the face cuts working perfectly just the way I want them but I cannot produce any turning cuts. It just says invaid toolpath. I have an alarm message which I will paste here: 

Error: Turning profile is split into two or more closed parts. You can avoid this error by modifying your model to ensure all parts of the profile are connected.

The model I am using is an igs file, a very fancy one of an impeller. My turning toolpath going over the solid part of the big turn but I guess fusion does not think so.

Does anyone have any ideas?

Thanks,

Mike

Try turning on Spun Profile in your Setup. You may need to activate Spun Profile Smoothing as well.

Neal,

I put a lot of work into this file but no real progress yet. I started over and redid the assembly and got back to a good facing toolpath right away but I am still having trouble with the turn. I took your advice and checked Spun Profile and Smoothing and that got me a toolpath on the small hub turn but not large turn that I need. Before it would not make a toolpath on either turn so it looks like a step in the right direction. I am thinking that the open passages for the water are causing trouble for the big turn.

I am running out

Thanks for the help,

Can you share your part here? I suspect it has something to do with the interrupted profile along the X axis definition (this is how it creates the spun profile). Sometimes you have to specify an axis direction so the profile is whole.
