Abstract
Presently, simulation models in virtual CNC machining simulation can be generated using commercial CAD software to provide dynamic 3D interactive virtual environments specifically designed for visualizing and analyzing the functionality of CNC machine tools and the material removal processes. However, these models generated using different CAD software have distinct individual formats, and are difficult to use in another simulation environment. This paper proposes to use the STL (stereolithography) models as the common models in machining simulation for bridging the incompatibility between different CAD software systems. The simulation results in the STL model format can be immediately used in rapid prototyping to produce the prototype and design changes can be reflected quickly from these prototypes. This will serve as a useful guide for the designers to make the necessary changes along the design process.
