Abstract
Currently CAD/CAM systems have become more and more common in automated manufacturing to enhance the accuracy and efficiency of machining process. However, currently the CAM programming is still a labor-intensive task. How to analyze the shapes of the products, and how to identify a specific machining operation are mainly relied on the experience the CAM programmer. Therefore, the feature extraction system, which analyses the shape of 3D-model instead of CAM users, was developed in this research. This research enables CAM user who is lack of machining knowledge to generate more effective machining path. Moreover, corresponding machining methods can be automatically carried out to each manufacturing feature by utilizing developed system together with the existing CAM system.
