... as input for extracting die-casting features, which consists of protrusion or depression regions of the part. These features are classified into those with single, double, or multiple withdrawal directions. Geometric reasoning is used for feature recognition, which includes nested and interacting features...

...Nandakumar Sridharan; Jami J. Shah, ASME Fellow Most of the work in machining feature recognition has been limited to 2-1/2 and 3 axis milling features. The major impediment to recognition of complex features has been the difficulty in generalizing the characteristics of their shape. This two-part...

... steps: 1) feature recognition of beam components: 2) gradient-based shape optimization of these components by reducing a weighted compliance among all load cases. The main contribution is to propose a new scheme to automate time-consuming shape optimization processes on polygonal meshes with beam...
