I found that Owl carvings are popular.
this is carved in a 24" Birch burl slab that is 3" thick.
I took a photo of the burl with a tape measure on it, than used that image in Aspire to create a near duplicate of the burl using the Drawing tools and Node editing.
I hoped to have a clean .5" wood border inside the bark, but did not do a great job of determining center.
The carving was done using 3 tool paths, a 1/2" end mill for the roughing pass. (I only do this when the finish carve is so deep that the Spindle head might travel down far enough to contact wood in the finish carve).
2nd pass was .25 " ball mill with 14% step over, as I wanted the back ground rougher.
3rd pass only carved the Moon and the owl, and was a .125 Ball nose with 9 % step over.
Pictures of the set up , just out of the CNC and the final shot after some detail carving, and sealing.
Thanks for looking
