Screw rotor manufacturing via 5-axis flank CNC machining using conical tools 

Bizzarri, M.; Bo, P.; Barton, M.Autoridad BCAM (2022-12)
We propose a new method for 5-axis flank computer numerically controlled (CNC) machining of screw rotors using conical tools. The flanks of screw rotors consist of helical surfaces, which predetermines the motion of the ...

Machining-induced characteristics of microstructure-supported LPBF-IN718 curved thin walls 

Mishra, S.; Escudero, G.; Gonzalez, H.; Calleja, A.; Martinez, S.; Barton, M.Autoridad BCAM; Lopez de Lacalle, N.; Mishra (2022-07)
The microstructure-supported design of engineering components is recently gaining attention due to their high strength-to-weight and high stiffness-to-weight properties. The present study investigates the hybrid manufacturing ...

Efficient 5-axis CNC trochoidal flank milling of 3D cavities using custom-shaped cutting tools 

Bo, P.; Fan, H.; Barton, M.Autoridad BCAM (2022-05)
A novel method for trochoidal flank milling of 3D cavities bounded by free-form surfaces is proposed. Existing 3D trochoidal milling methods use on-market milling tools whose shape is typically cylindrical or conical, and ...

Curve-guided 5-axis CNC flank milling of free-form surfaces using custom-shaped tools 

Rajain, K.Autoridad BCAM; Sliusarenko, O.Autoridad BCAM; Bizzarri, M.; Barton, M.Autoridad BCAM (2022-03)
A new method for 5-axis flank milling of free-form surfaces is proposed. Existing flank milling path-planning methods typically use on-market milling tools whose shape is cylindrical or conical, and is therefore not ...

On numerical solution of Fredholm and Hammerstein integral equations via Nystr\"{o}m method and Gaussian quadrature rules for splines 

Barrera, D.; Barton, M.Autoridad BCAM; Chiarella, A.; Remogna, S. (2022-01)
Nystr\"{o}m method is a standard numerical technique to solve Fredholm integral equations of the second kind where the integration of the kernel is approximated using a quadrature formula. Traditionally, the quadrature ...

5-axis double-flank CNC machining of spiral bevel gears via custom-shaped tools – Part II: physical validations and experiments 

Gomez, G.; Bo, P.; Gonzalez, H.; Calleja, A.; Barton, M.Autoridad BCAM; Lopez de Lacalle, N. (2021-10)
Recently, a new methodology for 5-axis flank computer numerically controlled (CNC) machining, called double-flank machining, has been introduced (see “5-axis double-flank CNC machining of spiral bevel gears via custom-shaped ...

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 ...

The Construction of Conforming-to-shape Truss Lattice Structures via 3D Sphere Packing 

van Sosin, B.; Rodin, D.; Sliusarenko, H.; Barton, M.Autoridad BCAM; Elber, G. (2020-11)
Truss lattices are common in a wide variety of engineering applications, due to their high ratio of strength versus relative density. They are used both as the interior support for other structures, and as structures on ...

Manufacturing of screw rotors via 5-axis double-flank CNC machining 

Bizzarri, M.; Barton, M.Autoridad BCAM (2020-11)
We investigate a recently introduced methodology for 5-axis flank computer numerically controlled (CNC) machining, called double-flank milling [1]. We show that screw rotors are well suited for this manufacturing approach ...

Characterizing envelopes of moving rotational cones and applications in CNC machining 

Skopenkov, M.; Bo, P.; Barton, M.Autoridad BCAM; Pottmann, H. (2020-10)
Motivated by applications in CNC machining, we provide a characterization of surfaces which are enveloped by a one-parametric family of congruent rotational cones. As limit cases, we also address ruled surfaces and their ...
