Scallop Height.
Determine the theoretical cusp/scallop height generated by a ballnose tool during a surfacing stepover.
Scallop Height
The Mathematics
Scallop height determines the theoretical surface finish (Ra) of a 3D contoured surface before polishing.
Formula
Scallop = (Tool Dia / 2) - √((Tool Dia / 2)² - (Stepover / 2)²)
