On tool wear optimized motion planning for 5-axis CNC machining of free-form surfaces using toroidal cutting tools

Supplementary dataset of the propeller model presented in our article [1]. We evaluated our method on a propeller surface and designed motions for the machining of one of its blades. Multiple experiments were conducted with varying weights in the optimization process to minimize tool wear and optimize machining accuracy. The bounding box of the blade is 10.5*12.2*4.6 cm, and the tool radii are R=1 cm and r=0.25 cm. The ‘models’ folder contains models in STL format: the blade the full propeller the body only (the propeller without the blade) The ‘paths’ folder contains 28 contact paths (trajectories) defined on the blade. Each file represents a path as a polyline. Each line of a file contains the three coordinates of the contact point. The ‘motions’ folder contains the optimized motions of the toroidal tool with various weights. (w = (0, 0.5, 0.8, 1)). Each folder contains 28 files corresponding to the contact paths. Each file contains nine coordinates per line: contact point (first three coordinates) center of the torus (second three coordinates) normalized axis direction (last three coordinates) [1] Kruppa, K., Zaragoza Chichell, J., Bizzarri, M., Bartoň, M. “On Tool Wear Optimized Motion Planning for 5-Axis CNC Machining of Free-Form Surfaces Using Toroidal Cutting Tools.” Computer-Aided Design 189 (December 2025): 103952. https://doi.org/10.1016/j.cad.2025.103952.
