Full Version: Spiral following an outline inside a closed curve

Hi BurrMan,

using a CAM software is a good idea if the software is able to create a bare spiral. I followed your proposal and tested different toolpaths created by different milling strategies. The best result is attached (blue lines). But the CAM software is not creating a spiral and is automatically doing S-linking between the different offset lines. There is no option to get the CAM not doing that.

you'll need to be able to do some type of spiral pocketing. I think my software has it. I'll have to go crank it up and look in a few.

The ai is tricky to prompt to get results. Because it is actually a "Morph Spiral". Not just a standard pocket or boundary pocket

Here is me attempting to get results with your file

Started with to proper path

then tried to get more "revolutions"

Finally made it all the way to center with revolutions and lost ability to control step

Its getting complex

mostly outputs are rubbish.

Had better luck making progress with GROK and prompts to change its output. Still sortof painful to be any type of real solution for what you are asking...

Thank you for your efforts on this. It appears this task cannot be completed quickly using standard MoI tools. However, Michael showed a MoI-script that reduces the workload by helping to create the spiral manually.

The exploration of CAM was an interesting idea, though mine was unfortunately unable to generate the required construct in this case.

Ultimately, it seems that performing this task with standard tools is difficult without custom coding. Unless this is a task we need to perform daily, the manual script solution likely remains the most efficient approach.

Hey Joerg,
Not for lack of trying, eh!

Looked at my CAM software. What we are doing is called a “morph spiral” and its more complex for sure.

It was a good exercise looking at how ai failed with the “more complex” parts of the solve. It definitely highlighted what the “complex” part is. Thats where rubbish was returned

Happy trails….

Hi Joerg,
1 last note. A side note.

Thought about it more and vector programs can do this pretty easily. So draw a spiral then “fit it to another shape” basically.

Just in case you can do that as an option
