How to turn 3d emboss on a cylinder with 2 axis lathe.

[louispregler]

I saw a video where a guy was turning 3d embossed shapes into a cylinder on a 2 axis lathe. As a thought experiment I wanted to try it but it seems even with radial and axial turned on it just won't simulate this or allow this. any ideas or work around for this?

Hi

You cant do this with a 2 axis lathe, you could with a 3 axis though, you need XZC axes.

Its not really being "Turned" what's probably been done is a milling toolpath is created and then the code is been hand edited to replace the milling tool with a turning tool.

Heres the file with a Geodesic path

You will have to edit the code after posting to use a turning tool and set the appropriate feeds

It was definitely a 2 axis lathe, that's what fascinated me. I can't seem to find the original video but here is another couple more elaborate examples.

I guess the geodesic could work with quite a bit of manual editing. Was just hoping fusion had a way to calculate this without having to write some crazy macro.

 first one is described as a 2 axis lathe but MUST be monitoring the Spindle position with an encoder.

Notice this is done with a MACRO program at the controller not in any cam software.

The second one on Instagram is almost certainly done using the method I described above with a milling toolpath.

Its not too hard to edit the code, you just need to remove the milling spindle speeds and direction commands and use a turning tool in place of the milling tool.

The ball nose in Fusion should match the tip radius of the turning tool.

You will still need a C axis to do this though

Agreed, the 1st has to be macro controlled.

I don't have the extension to play around with the geodesic. I couldn't even post the code to look at it. I'm pretty confident it could work though given some time. I do have C axis control on my ST-10. I'm assuming I'd have to have a custom PP to handle the C locations as well instead of just a defined RPM.
