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 ...

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 ...

Reparameterization of ruled surfaces: toward generating smooth jerk-minimized toolpaths for multi-axis flank CNC milling 

Hashemian, A.Autoridad BCAM; Bo, P.; Barton, M.Autoridad BCAM (2020-05)
This paper presents a novel jerk minimization algorithm in the context of multi-axis flank CNC machining. The toolpath of the milling axis in a flank milling process, a ruled surface, is reparameterized by a B-spline ...

Machining of developable ruled surfaces using mathematical algorithms 

Calleja, A.; Gonzalez, H.; Polvorosa, R.; Amigo, F.; Gomez, G.; Fernandez, P.; Barton, M.Autoridad BCAM; Bo, P.; de Lacalle, N. (2020)

5-axis double-flank CNC machining of spiral bevel gears via custom-shaped milling tools -- Part I: modeling and simulation 

Bo, P.; Gonzalez, H.; Calleja, A.; Lopez de Lacalle, N.; Barton, M.Autoridad BCAM (2019-11-20)
A new category of 5-axis flank computer numerically controlled (CNC) machining, called \emph{double-flank}, is presented. Instead of using a predefined set of milling tools, we use the shape of the milling tool as a free ...

On initialization of milling paths for 5-axis flank CNC machining of free-form surfaces with general milling tools 

Bo, P.; Barton, M.Autoridad BCAM (2019-03-27)
We propose a path-planning algorithm for 5-axis flank CNC machining with general tools of varying curvature. Our approach generalizes the initialization strategy introduced for conical tools [Bo et al., 2017] to arbitrary ...

FREE-FORM TOOLS DESIGN AND FABRICATION FOR FLANK SUPER ABRASIVE MACHINING (FSAM) NON DEVELOPABLE SURFACES 

Gómez-Escudero, G.; Gonzalez, H.; Barton, M.Autoridad BCAM; Bo, P.; Fernández-Lucio, P.; Lopez de Lacalle, N.; Calleja, A. (2019)
Manufacturing improvements are becoming a real need in industry. In order to satisfy these industrial requirements, they should be targeted in two different directions: new manufacturing processes and surface optimization ...

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 ...

Automatic fitting of conical envelopes to free-form surfaces for flank CNC machining 

Bo, P.; Barton, M.Autoridad BCAM; Pottmann, H. (2017-10)
We propose a new algorithm to detect patches of free-form surfaces that can be well approximated by envelopes of a rotational cone under a rigid body motion. These conical envelopes are a preferable choice from the ...

Towards efficient 5-axis flank CNC machining of free-form surfaces via fitting envelopes of surfaces of revolution 

Bo, P.; Barton, M.Autoridad BCAM; Plakhotnik, D.; Pottmann, H. (2016-06-30)
We introduce a new method that approximates free-form surfaces by envelopes of one-parameter motions of surfaces of revolution. In the context of 5-axis computer numerically controlled (CNC) machining, we propose a flank ...
