I’m using a 2.5" sufacing bit on my spoinboard. F360 simulation shows the bit going outside the spoiboard dimensions by ~1.25" by the look of the simulation. That looks like it would take out the tool height setter.
This is probably a normal experience, but I’m not sure how best to handle it without damaging things.
PS. Forgive my ignorance. I’m new to the Avid and my old other CNC experience was a Yeti Smartbench that was drastically different in almost every way.
Fusion does some weird stuff with the way it does facing toolpaths. Its possible to make it better with the stock offset and path extension options and by tweaking the boundary curve that it is surfacing.
In Fusion you can change the direction in x or y for the toolpath. As greg mentioned, you can also change the path extension, both settings are in passes tab . The 1st pic is the path extension that Fusion defaults to with the tool being used. The 2nd is the same tool with the path extension set to zero.
Thank you for this! I’d started playing with it yesterday and found some of this out, but your confirmation is much appreciated.
I was having issues with an operatrion yesterday that had me frustrated, but eventually I figured out that my problems were all in my own Fusion file and got it going. Lots to learn.
Yeah, facing operations kinda assume there’s no other “stuff” to hit so by default it takes some liberties with overshooting. It might be better to use a pocket toolpath… At least by default you can really tightly define where the tool will go.
Thanks Eric, that’s a great idea.
The more I learn, the less I know.
