You are looking for something along the lines of the bottom left image on that 
web page? How thick would the black areas be compared to the white areas? It 
should be fairly easy hard to create a basic 3D model using that image as a 
guide. I have both Rhino 3D (surface modeller) and IronCAD (solid modeller). 
Would the CNC machine accept an IGES file for import or do you need something 
else? The programs I use can output several different file formats.
