technology can rival the barrier breaking impact of computers. This is especially evident in the advancement of CNC technology. For‚ cutting edge CAD/ CAM programs‚ Neural Networks (NN)‚ and super- fast processors have enabled computerized machining centers to make decisions without direct human input. These autonomous machines have progressed from enormous machines into compact milling marvels no larger than‚ depending on the application‚ a small office. The subject of this research paper will be

South Africa does not have enough very large size CNC machines on which these could be machined. A large size mould half can be split into two or more smaller parts for machining purposes and then reassembled later. In this way many large size moulds‚ especially rotational moulds can be manufactured on medium size CNC machines. Since the large component has been split into small parts‚ these can be distributed to different subcontractors to machine simultaneously‚ and thereby reducing the total manufacturing

package. The aim of the project is to generate the tool paths required to machine the part using a CNC milling machine. 2 CAD/CAM Systems A CAD/CAM system is a computer based platform used for manufacturing component parts on fully automated Computer Numerically Controled (CNC) production machines‚ generally milling machines or lathes. The CAD software produces geometries on PCs or laptops‚ the CAD file is exported to a CNC machine and a finished part is produced at the click of button. CAD/CAM systems
