  • Accessibility for Line-Cutting in Freeform Surfaces 

    van Sosin, B.; Barton, M.Autoridad BCAM; Elber, G. (2019-04-26)
    Manufacturing techniques such as hot-wire cutting, wire-EDM, wire-saw cutting, and flank CNC machining all belong to a class of processes called line-cutting where the cutting tool moves tangentially along the reference ...
  • Blisk blades manufacturing technologies analysis 

    Calleja, A.; Gonzalez, H.; Polvorosa, R.; Gomez, G.; Ayesta, I.; Barton, M.Autoridad BCAM; de Lacalle, N. (2019-06)
    The paper presents blisk blades manufactured by different manufacturing processes. In this sense, different milling trajectories are presented, and, super abrasive machining strategies and EDM technologies are also tested. ...
  • Gaussian quadrature for $C^1$ cubic Clough-Tocher macro-triangles 

    Kosinka, J.; Barton, M.Autoridad BCAM (2018-10-31)
    A numerical integration rule for multivariate cubic polynomials over n-dimensional simplices was designed by Hammer and Stroud [14]. The quadrature rule requires n + 2 quadrature points: the barycentre of the simplex and ...
  • Geometry and tool motion planning for curvature adapted CNC machining 

    Barton, M.Autoridad BCAM; Bizzarri, M.; Rist, F.; Sliusarenko, O.Autoridad BCAM; Pottmann, H. (2021)
    CNC machining is the leading subtractive manufacturing technology. Although it is in use since decades, it is far from fully solved and still a rich source for challenging problems in geometric computing. We demonstrate ...
  • Highly-accurate 5-axis flank CNC machining with conical tools 

    Calleja, A.; Bo, P.; González, H.; Barton, M.Autoridad BCAM; Lopez de Lacalle, N. (2018-04)
    A new method for $5$-axis flank computer numerically controlled (CNC) machining using a predefined set of tappered ball-end-mill tools (aka conical) cutters is proposed. The space of lines that admit tangential motion of ...
  • Optimally refined isogeometric analysis 

    Garcia, D.; Barton, M.Autoridad BCAM; Pardo, D.Autoridad BCAM (2017-06)
    Performance of direct solvers strongly depends upon the employed discretization method. In particular, it is possible to improve the performance of solving Isogeometric Analysis (IGA) discretizations by introducing multiple ...
  • Super Abrasive Machining of Integral Rotary Components Using Grinding Flank Tools 

    González, H.; Calleja, A.; Pereira, O.; Ortega, N.; Lopez de Lacalle, N.; Barton, M.Autoridad BCAM (2018-01-01)
    Manufacturing techniques that are applied to turbomachinery components represent a challenge in the aeronautic sector. These components require high resistant super-alloys in order to satisfy the extreme working conditions ...
  • Towards optimal advection using stretch-maximizing stream surfaces 

    Barton, M.Autoridad BCAM; Kosinka, J. (2017-03-01)
    We investigate a class of stream surfaces that expand in time as much as possible. Given a vector field, we look for seed curves that locally propagate in time in a stretch-maximizing manner, i.e., curves that infinitesimally ...
