High-speed machining with Autodesk Fusion 360

I decided to try Fusion's 30-day trial. Here's how it did:

Very interesting. I have not checked out actually using Fusion 360 for any real work yet.
The HSM looks great for roughing, but not so great for finishing. It appears that you get a lot of deflection in your spindle and some odd artifacts in your tool path.
Good job on playing with it though, I look forward to seeing more examples!

Here's an example of when things go wrong (slow-mo):



I set it up for the wrong cutter diameter. Config = 1/4", Actual = 1/8". Red Oak.

Hey tbfleming,

Can you describe a little more detail about what you've done here?

What sort of step over ("optimal load") are you using? Any strategy for picking this? Could you share your grbl settings? (In particular curious about accelerations.)

I have a similar setup I think: 0.9g, Dewalt 611 in custom mount, Acme Z, otherwise stock. Any non-obvious machine mods on your end?

I've been using a more conventional/conservative strategy (~60-90 in/min, diameter / 2 stepdown / over) and I'm going to experiment with more aggressive options.

I'm really liking Fusion. It's the first program I've found (for the mac at least) that gets me from concept to construction in one go.

Thanks for sharing!
