Towards $G^1$-continuous multi-strip path-planning for 5-axis flank CNC machining of free-form surfaces using conical cutting tools
(2023-06)
Existing flank milling path-planning methods typically lead to tiny gaps or overlaps between neighboring paths, which causes artifacts and imperfections in the workpiece. We propose a new multi-strip path-planning method ...
Efficient 5-axis CNC trochoidal flank milling of 3D cavities using custom-shaped cutting tools
(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
(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 ...
5-axis double-flank CNC machining of spiral bevel gears via custom-shaped tools – Part II: physical validations and experiments
(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 ...
5-axis double-flank CNC machining of spiral bevel gears via custom-shaped milling tools -- Part I: modeling and simulation
(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
(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 ...
Highly-accurate 5-axis flank CNC machining with conical tools
(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
(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 ...
