Corel Draw creates a Vector file that the print driver understands. CNC machines can import Vectors, DXF files, SVG files, Illustrator files, Corel Draw files, DWG as line drawings. If you're doing 3D models then your formats are going to be .obj, .stl, etc. Your software then takes whatever toolpaths you've created along with the post processor for your machine and then generates the GCode for that particular controller that you then load your GCode into either directly from your computer or via a USB drive.
Some programs just create the vectors, while others create the vectors and the GCode.
