Abstract: This paper presents a novel tool path planning approach for polygonal mirror scanning based stereolithography (STL) process. Compared with traditional laser scanning and mask projection based STL process, the polygonal ...

Abstract: For integrating different constraints from robot’s tasks, such as geometry, kinematics, and dynamics, with trajectory planning and robot motion control, a two-layer robot trajectory planning structure ...

Abstract: Despite the complexity and importance of friction, most current simulations of metal-forming processes use relatively simple friction models such as the Amontons-Coulomb constant friction coefficient. ...

Abstract: The authors present a new set of tools for solving the one-dimensional Saint-Venant equations (1D-SVEs) of flow transport throughout dendritic river networks. The numerical solver is integrated with a set of geoprocessing ...

Abstract: Digital maskless lithography is gaining popularity due to its unique ability to quickly fabricate high-resolution parts without the use of physical masks. By implementing controlled grayscaling and exposure control, it has ...

Abstract: Additive manufacturing technology provides the possibility of more efficient turbine cooling structures. In this work, a novel structure for turbine air-cooled vane based on fractal structure, named scale cooling structure, ...

Abstract: A class of problems that has received considerable attention in recent years from both control theorists and engineers is the following: Given ẋ = Fx + du, x(0) = cDetermine |u(t)| ≤ 1 ...

Abstract: The dynamic response (structure borne noise) of two cross beams intersecting perpendicularly to each other is studied for a point load applied vertically at an arbitrary location on one beam. ...
