Machining angled surface which is turning inwards
I'm trying to make toolpath for part side surface which is 89 degrees from the top surface. To achieve this I'm using dovetail cutter. However I'm not succeeding in making toolpath which would follow the surface. I'm using the 3D parallel toolpath and I succeeded to make this if the angle is 91 deg with endmill. Is it that Fusion 360 just can't do this when you need to go "inside" direction? Attached picture of the scenario and red line shows the surface need to be machined.
Thank you in advance.

You'd actually want to be using a 3D Contour for this. Note; with a sharp corner tool, the surface finish is going to be very rough unless you use an extremely small stepdown
I've attached a sample file showing the method used

Thank you for replying. Is there any way to change the toolpath 90 deg?
If having horizontal toolpath the surface would be like sawtooth..

This is as close as I can get it to work, still it won't do the taper.. Hopefully there is some other way than shim the part to 1 deg and finish that surface by endmill. Even any dirty hack/trick to fool it to think it's 91deg instead of 89 or something..

No, parallel does not recognize undercuts, 3d Contour would be your only option, unfortunately

Could this functionality be added to the list of future developments perhaps? ![]()

We are working on improving our "undercut" machining strategies, so it's possible that a future release would give better tools for this. No timeline on that though, as the work is still in the "idea" phase
