Just drew up a part and camed. Seems that fusion turning is quit robust. I used a groove/turn tool and it gave me 2 or3 toolpath options. The simulation is great too. When you turn the stock on the part looks rendered when it is machined. Looks very realistic. I am impressed thus far with it, but didn't post any code yet.

Great, let us know how it goes once you post.

I've been trying to cut a simple part using Fusion360.

no matter what settings / strategy I use, I always see rounded corners on the simulation and G3 calls in the profiling section.. On a straight profile??
The model doesn't have a single angle or arc on it.

I've tried it on two separate computers and also tried it using Inventor 2016.
All do the same.


Model:
Attachment 291922

Note arc in tool path:
Attachment 291924


Note G18 and G3 in code.

Just messing around and I suppressed the center hole / threading.
No more arc moves in the profile code!

That's when the second error came to my attention.
In the grooving section it's doing two groove cuts to form the small feature.
First groove goes down to 0.22", second goes down to 0.20" so my cut part has a step in the feature.

Is there a CAM solution for turning that works??
For something like this it's probably easier to learn G-code and code it myself.

[jdholbrook]

Seems HSM thinks drilling and tapping are mill operations and this screws up the path generation for turning.
The solution suggested is to edit the Post Processor.

Find the line that reads "capabilities = CAPABILITY_TURNING;" and change it to "capabilities = CAPABILITY_MILLING | CAPABILITY_TURNING;"

I haven't tried it yet as I'm not in the shop today.

What kind of groove/turn tool do you use? I am looking for one and have no idea what to get??

mpix00,

I am using a Shars MGEHR3/4 Multidirectional tool.
