Cusp height formula milling stepover distance calculator as a result a small cusp of material called a scallop will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used the size of the stepover distance and the tool diameter will determine the scallop height between each step
For example if you are using a radius mill as opposed to a ball mill any flat horizontal surface will probably be machined at the stepover setting scallop height 0 whereas contoured surfaces will be governed by scallop height and the corner radius of the end mill
Dec 15 2011 im just wondering what everybody prefers to use when 3d milling with ball mills my dealer tells me that old school people use step over by distance while new school programmers use the scallop height well i guess im old school ive always used step over by distance im finishing a race track shape with a 18 ball
