Circular facing op with non-round part?

Circular facing op with non-round part?

I'm machining a semi-rectangular part, with a hole in the center, from 12" round stock.

I'd like to face it with a spiral pattern from the outside in.


I tried creating a sketch the same size as the stock to create a boundary, but the cutter stays inside this boundary, even with tool outside boundary set.


I've tried 2d adaptive, spiral, and morphed spiral to no avail.


Are there any videos/simulations out there showing how to get a spiral facing op?

Thank you!

Would you be able to share your Fusion file here?

2D contour around your hole 



I use 3D flat, it does a nicer job.

Your second photo is exactly what I'm trying to do. 

What the heck settings do I use to get it to start from the outside, of my round stock, and continue to the center like yours does??

Edit: Hopefully this photo works.

Double edit: Thank you both for the replies!

Here is the F3D of the part.

I was hoping there was a spiral facing option under the face op!

Click patch, click your circle, then select that surface in your toolpath. 

If you modelled your stock, you can also just select that.

GAHH. Turning the raw stock sketch into a patch solved everything.
That's a fantastic tip that will be helpful everywhere.

Thank you so much!
