Abstract: While additive manufacturing allows more complex shapes than conventional manufacturing processes, there is a clear benefit in leveraging both new and old processes in the definition of metal parts. For example, one could ...

Abstract: This paper is arranged in three main sections: the first section is a hierarchical method based on clustering and a fuzzy membership system where the tessellated three-dimensional (3D) models are classified into their ...

Abstract: In this paper, we present multiple methods to detect fasteners (bolts, screws, and nuts) from tessellated mechanical assembly models. There is a need to detect these geometries in tessellated formats because of features ...

Abstract: A new graph grammar based reasoning is proposed to reason about the manufacturability of 3D solid models. The knowledge captured in the graph grammar rules serves as a virtual machinist in its ability to recognize arbitrary ...

Abstract: With the increase in computercontrolled hybrid machining (e.g., millturn machining), one needs to discern what features of a part are created during turning (i.e., with a lathe cutter) versus those created by milling. Given ...

Abstract: Advanced joining processes can be used to build-up complex parts from stock shapes, thereby reducing waste material. For high-cost metals, this can significantly reduce the manufacturing cost. Nevertheless, determining how ...

Abstract: As computer aided design (CAD) tools become more sophisticated, engineers are able to more easily create complex part geometries with minimal mass given strength and stiffness requirements. However, these complex part ...

Abstract: Impact forces are a destructive, yet common occurrence in legged locomotion. Every step produces a collision when the leg’s inertia stops as a result of ground contact. This results in peak forces and high-frequency ...
