Milling Process Defects Equipment

End milling an end mill makes either peripheral or slot cuts determined by the stepover distance across the workpiece in order to machine a specified feature such as a profile slot pocket or even a complex surface contourthe depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple
