Surface Project

[JMahon]

So I am making wedding bands for me and my fiancé.

 

I would like to project our names to the inside of the ring... anyone care to help a brother out?

 

File is attached.

RING.MCX-7

Had to clean up the solid since I don't have solids, converted to surfaces, created drafting, went to front view. Broke drafting into lines, projected lines onto inside surface of ring. Selected just lines and transformed them to be slightly in front of the ring so you could actually see them.
 
You're talking something like this ya?

 

Ended up looking like so.

if you yous roll it will rap around  if the names are longer

I can't open the file till tomorrow, but I think I got the text part but what about a toolpath?

It's on a 5 axis mill. I was thinking of kicking it at a 45 or so and then engraving.

Axis sub?

Hey mike you think you could post a screen shot of the suggested axis sub parameters to make that work? I tried a few things but it wraps it way to big.

Here's a quick little video that will show you one way to project,

Ya, but do you really think his girlfriend wants a ring that says J Paris inside?

Nope, I think he can add his own engraving.....

I got the project part... What about cut parameters to make axis sub work. I'm stumped.

If you are doing this on the inside of a ring, I am thinking axis sub isn't going to be what  you need for a toolpath

 

More likely a 5 axis curve with some tilt so you can get the tool in there and get some rotation

 

Not perfect bit more massaging perhaps but I think you'll  get the general idea

Depending on how much the text wraps around the inside of the ring you should be able to do it with a simple 3-axis toolpath.  I would kick it over at 30-45 degrees and machine it with a tiny ball mill.  As long as you are machining with the ball and not the cylindrical portion of the tool you will get the same results as a 5-axis toolpath.  If the text spans 180 degrees you can either try a 5-axis toolpath or engrave it in sections with 2-3 re-positions.  I always try to keep it simple so I would just re-position and machine with a 3D contour.
