Abstract
The 5-axis NC machining has been important issue in manufacturing today. Products are manufactured from designers to market with CAD/CAM software. In the process of the computer-aid design and manufacturing, it is necessary for NC tool path verification whether the cutter location data and NC code is correct or not. Computer visual reality cutting provides the user intuitively to get modeling correctness.his research simulates the cutting situation of 5-axis machining. The data structure is based on voxel and adaptive octree. Using the APT function with marching cube algorithm, the memory is reduced and logical determination can avoid the repeating calculations;Therefore, the system is increased in the efficiency and display on the real-time cutting situation. The program can read cutter location data, 3-axis or 5-axis NC code from various CAD file formate. The system can also be enhanced by using triangle mesh data as rough file input.
