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.

Diagram comparing cutting tools with different edge radii, showing that larger radii enable a larger axial depth of cut and better surface finish. The left side shows a tool with an edge radius of 1.22 micrometers and a cutting edge radius of 0.5 millimeters, while the right side shows a tool with an edge radius of 0.46 micrometers and a cutting edge radius of 1.5 millimeters.
