Milling Process, Defects, Equipment

End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The 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 passes.
