Actually, forget what I wrote above. I can get the roughing, waterline and pencil finishing, but cannot finish the broad “absent” areas because there is nothing to machine there. So I get a roughed carving with nice edges but not the finished flat bottom. This logo can’t be machined from the SVG/DXF as input.
An STL with material under the recesses, (or a B/W bitmap processed as a bitmap) would be possible to do.
@FlatBaller, I do the machine regions too on occasion. I machined these louver simulations a row at a time to reduce the back-n-forth.
There was a lot more machining, then it looked like this
Then I bent it up to prototype what would be a punched sheet metal enclosure.
Prototype on top, production enclosure on bottom
But that’s far afield. Louvers machined using MeshCAM, broad cleanout machined using SheetCAM, all on my Tormach. Simulating a .063" aluminum enclosure with .125" high punched louvers by machining a .188" thick plate…
