Trace path on an irregular surface using a rotary axis.

[silviaaday]

Hello experts, i have been pushing my limits with this, very new to Fusion. I have a model made out of a mesh and a solid, i can successfully cut it using "Rotary Parallel", the next step is to trace a design on the solid (Not perfectly cylindrical). I have been able to use the 2D tool paths to do this however the depth and shape are not consistent since the part is not rotating therefore the tool is not always perpendicular to the surface. I'm using a CNC router with a rotary axis (A), no tilting features. I've been trying to rotate the part as the trace is being cut. Any help will be highly appreciated. Thanks, Silvia

Trace does not support a "wrapped" (or rotary) toolpath. However, Project does, provided you enable 5-axis and set the Primary Mode "To Curve" and select an axis that runs thru the centerline.

This will likely require the MFG Extension.

And if you could share your toolpath here, I'd be happy to try out a couple options for you.

Thanks for the quick response. I tried the Project path with your recommendation, it generates but i get a generic error in posting (! Error: Failed to post data. See log for details.). Would the fact that the machine has 4 axes be the issue? File attached. Thanks

is your post processor configured for 4 axis motion?

Hmm. It's failing for you because of your selection for "To Curve". Ideally, we want to select a single axis that goes thru the part centerline, but when I do so, I get an empty toolpath 🤔

The processor is set for 4 Axes, i’m able to post other rotary paths.
