I want to share with you a project we have made with one of our student : it is to mill a tower of a chess game. The tower is a special one : the model exists on our campus : Arts Et Métiers (Cluny).
We programmed all the part with 3dExp (and simulate with the machine as you can see in the video) and our Post Processor is NCSOFT. We have also an external software to simulate the G-code. 
 

Here the video : 

On the picture it is the final part after sandblasting.
