These are my first experiments with 3D carvings on our 3 axis CNC milling machine. It was interesting seeing the huge difference in machining time between the two geometry types I tried. As the smooth ripple surface can run each pass of the tool in one continuous line, without stopping, it is a much faster surface to produce. At every peak the Hendeca surface would have to stop the machine and change direction, slowing progress significantly, so much so that I didn’t get around to finishing it. I do quite like the effect of the roughing pass though…overall a good lesson into the relationship between effective modeling/milling techniques.
