Obtaining a spiral path for machining STL surfaces using non-deterministic techniques and spherical tool ?
Machining STL surfaces, without a volume inside, is useful and it can be optimized. To optimize this process we use the piece contour, defining 2D spiral paths. With non-deterministic techniques, the third coordinate of the tool-path is obtained. This method was simulated and applied to a workpiece, with positive results. Its precision was tested using confocal microscopy and coordinate-measuring machine.
