    Compendium of publications on: differential operators on manifolds for CAD CAM CAE and computer graphics
    (Universidad EAFIT, 2020) Mejía Parra, Daniel; Ruiz Salguero, Oscar Eduardo; Posada Velásquez, Jorge León
    This Doctoral Thesis develops novel articulations of Differential Operators on Manifolds for applications on Computer Aided Design, Manufacture and Computer Graphics, as follows: (1) Mesh Parameterization and Segmentation. Development and application of Laplace-Beltrami, Hessian, Geodesic and Curvature operators for topology and geometry – driven segmentations and parameterizations of 2-manifold triangular meshes. Applications in Reverse Engineering, Manufacturing and Medicine. (2) Computing of Laser-driven Temperature Maps in thin plates. Spectral domain - based analytic solutions of the transient, non-homogeneous heat equation for simulation of temperature maps in multi-laser heated thin plates, modeled as 2-manifolds plus thickness. (3) Real-time estimation of dimensional compliance of hot out-of-forge workpieces. A Special Orthogonal SO(3) transformation between 2-manifolds is found, which enables a distance operator between 2-manifolds in R^3 (or m-manifolds in R^n). This process instruments the real-time assessment of dimensional compliance of hot workpieces, in the factory floor shop. (4) Slicing or Level-Set computation for 2-manifold triangular meshes in Additive Manufacturing. Development of a classification of non-degenerate (i.e. non-singular Hessian) and degenerate (i.e. singular Hessian) critical points of non-Morse functions on 2-manifold objects, followed by computation of level sets for Additive Manufacturing. Most of the aforementioned contributions have been screened and accepted by the international scientific community (and published). Non-published material corresponds to confidential developments which are commercially exploited by the sponsors and therefore banned from dissemination.

    Proceso de ASC - USOS Y APLICACIONES DE LA ARCILLA DE PROTOTIPADO-CLAY EN EL ECOSISTEMA DE MANUFACTURA DIGITAL CAD-CAM-CAE DE LA ESCUELA DE INGENIERIAS.

    “Industrial or prototyping clays” (Industrial Clay) are materials malleable and moldable to make three-dimensional models and for their properties it is possible to use them and re-use them again, without having to waste material or discard already made models during the process. For his Constitutive characteristics offer great versatility; since they can be worked both manually (sculpted) or digitally (CNC routing among others). From the latter, and as part of the final clay implementation process in the laboratories of the EAFIT university; it is necessary to determine the possibilities of application and use of the material; in the ecosystem of digital manufacturing of numerical control technologies or 4.0 (CAD/CAM/CAE): Robot, Lathes, Milling Machines, Routers, Cutting Machines, etc. In order to deploy its potential in other applications that are still have not been explored. Likewise, it is intended to generate the bases regarding parameters, considerations and variables to take into account for the material in these processes and their future applications.
