• Machinist CalculatorsVilla Machine Associates Inc.

The "SURFACE FINISH" calculator also includes a stepover adjustment calculator for internal and external radii. A ballnose end mill makes smaller scallops on an internal radius and larger scallops on an external radius and so it must be adjusted to maintain consistent surface finish.

• Ra RMS Surface Roughness CalculationSurface Finish

The electropolishing process may improve a surface finish by up to 50 . The electropolishing reaction removes material while it improves surface roughness. Because of the material removal process runtimes are often limited to maintain dimensional tolerances. Limited runtimes result in real world surface roughness improvements from 10 to 35 .

• Milling surface generation Coromant

To generate the best milling surface finish it is important to ensure that the feed per revolution (f n = f z x z n) is less than 80 of BS.As cutter diameter increases (and for extra close pitch cutters) the number of teeth as well as feed per revolution increases requiring a larger BS.

Jul 30 2013 · Basically stepover is the distance between each pass of the machines tool head. The image (above) shows a tool head on a job. The tool path is directly to and away from you in and out of the image. It is not the main factor influencing the final surface finish as the tool used will largely determine the cusp height.
