Abstract
The machining of complex products which have specific geometries and accurate dimensions is vital for industrial competition. This work presents a methodology for the automatic generation of tool paths required to machine Three-Dimensional (3-D) surfaces consisting of cavities or free form shapes. The proposed system starts with the creation of the wire frame drawing for the surface of the required mechanical system. Based on the created drawing, several procedures component using a CAD are performed to automate the tool path generation of a process plan which contains detailed information needed in the NC machining process. These procedures include extracting the coordinates of surfaces nodes, arranging these databases to several cutting planes, and the self identification of the geometrical shape of the surface. The geometrical shape of the surface may consists of a cavity or free form shape. Based on the geometry of the surface, the proposed system generates the tool paths for both the roughing and finishing operation required to produce the required surface.
