To run the software, click the link above.

The software imports STL file format. It then calculated the rough and final cuts, and generated a G-code file for a ball-end router bit on a standard 3-axis CNC vertical milling machine. The software has been extended to automatically cut the upper and lower sorfaces from a single block by flipping it over.

Any CNC vertical milling machine can be used providing the working dimensions are sufficient and the machine controller is able to input G-code files. The University of Brighton has two such machines. The first machine (shown on the left below) is a Kryle VMC700M with a maximum working volume of 700mm x 450mm x 400mm.
