Assuming backlash-free ball screws are used, the downcut is preferred over the upcut milling. Upcut Milling . During upcut milling, the end mill pushes away from the workpiece, which, when only removing little chips, quickly causes the cutting edge to push out of the workpiece. This leads to chatter marks which create an unclean surface and reduce the endurance of the end mill.
احصل على السعرEnd milling is the most versatile form of milling that can be used to machine slots, shoulders, die cavities, contours, and profiles. An end milling process consists of a cylindrical cutter that has multiple cutting edges on both its periphery and its tip, permitting end cutting and peripheral cutting. These cutting edges or flutes are usually made helical to reduce the impact that occurs
