Ask away, someone will have an answer. I have used my cnc mill to cut inlay pieces for my pens although probably not in the materials you will use. The end results are still the same.
 
One of the easiest ways to do inlays on CNC is to carve out the pattern and fill with colored epoxy or polymer clay. Helps tremendously if you have a rotary axis. Would be a good start.
 
ok so the first question i have is. I assume you mill the inlay while the blank is round. maybe just proud of size? not square. I wish i have a 4th axis. but for now i will do it two sided. I also assume you use a normal end mill. not a vbit. i know in doing other larger inlays. Vcarved inlays come out nicer less if any gaps.
 
What I have done is turn the blank a little oversize, then mount in machine. I run the pocket with a small, .031 diameter endmill. You have to watch out for how wide the inlay is so not to go too far off center, or you will have little depth on those edges. You can make some sort of indexer to rotate the blank evenly spaced for three or four 'sided' pockets.
 
Thank you Paul. I work in a machine shop. So i have made a 6 sided block that will hold a short mandrel. And i have a .022 endmill. I am going to start out simple with like a pool cue diamond or something.

That was one of my first ones as well. I will try to find a pic. Working in a machine shop does have its advantages for a thing or two, I have been a machinist for over 40 years now. I did my inlay part in a cnc bridgeport mill. Looked like I was working on a toothpick:)
 
There is a program called Estlcam. It allows you to set a design and specify whether you want the tool path to be inside the line, on the line, or outside the line.
 
Found a pic.
