Tested surface quality

Compared to machining with ball milling cutters, the theoretical scallop height does not change significantly with larger line increments. This was proven in real-life applications using surface testing methods. A reference surface was machined using a ball cutter with a radius of 3 mm and a barrel cutter with a radius of 350 mm. While the quality of both surfaces was nearly the same, the machining time was 90 percent shorter using the barrel cutter.
