I was way too conservative on my feedrates for this piece, I am still getting a grip on rotational speeds, instead of inches per minute it is in degrees....
This piece took much longer then it should have, roughing and finishing passes probably took 3 hours combined or more (I normally record all carving times, but not this time as I was still getting everything setup. I will run another rotary job and take good notes).
The nice thing about generating toolpaths for the rotary axis, you can use whatever you are familiar with. If you are setting it up from scratch, you have to setup the cylinder as if it was unwrapped and laying out flat. So your workpiece is simply length x circumference. You can use any of the cam programs to do this, I generated a few to test and then used CNC Wrapper ( http://www.cncwrapper.com/ ) to process the toolpath into a rotary toolpath.
Aspire does a great job of unwrapping your cylinder as well. From what I have read Fusion360 can also do this...as well as a number of programs.
The carve above was done using an STL file, I think I got it off of Ebay in a bundle of STL files. I processed the job using Aspire and their Mach3 rotary post processor.
Edit: I also used CNC Wrapper to generate the toolpath that rounded the oak board into a cylinder. The board was about 2" x 3" and I ended up with a 2" diameter cylinder.
