Manufacturing of screw rotors via 5-axis double-flank CNC machining – BCAM
Each folder contains the mesh files of the target geometry (screw rotor) and of a corresponding custom-shaped tool.  The motions of the tool are described as the CL files, where each line in these files contains the information about the tool tip (first 3 coordinates) and the unit vector of the tool’s axis (last 3 coordinates).
Geometry and tool motion planning for curvature adapted CNC machining – BCAM

 

Examples of 5-axis CNC machining tool paths and corresponding g-codes for a concave, convex and a freeform surface milling with a toroidal cutter (supported information for the paper “Geometry and tool motion planning for curvature adapted CNC machining”, DOI 10.1145/3450626.3459837).

In the ‘path.txt’ files, each line contains three numbers that are Euclidean coordinates of the contact points; in the ‘positions.txt’ files, each line contains six numbers: the first three being the coordinates of the centers of the torus and the other three being the coordinates of the unit axis vector of the tool, pointing outside the surface.

Winged duck – Technion An example of a trimmed trivariate volumetric model (VModel), populated with trivariate microstructures.  The microstructures in the file have different  colors depending on their types: green tiles are fully inside the primitive trivariates of the winged duck (e.g. body, and two wings),  red tiles are the special bridging tiles connecting the body and the wings, and yellow tiles are the inside tiles used in anchoring  different primitives of the model. Each tile trivariate is given a unique integer ID and stores the additional information such as  the neighboring trivariates, the parametric domain in which the tile occupies (in case of the regular tile only) and colliding trivariates  (in case of bridging tiles only made from sweeping only) in its attributes. Duck model is provided, in IRIT (https://www.cs.technion.ac.il/~irit/) ITD file format, as trivariates, and in IGES file format as surfaces. Related publication.
