WEBDisadvantages of climb milling. In contrast to downcut milling, in upcut milling the tool is guided against the direction of rotation. Thus, the chip thickness starts at zero and keeps increasing. Since the cutting edge has to be driven into the cut, higher temperatures and a polishing effect are created on the surface of the workpiece.
