Climb Milling vs. Conventional MillingIn The Loupe
May 05, · In Conventional Milling, the cutter rotates against the direction of the feed. During Climb Milling, the cutter rotates with the feed. Conventional Milling is the traditional approach when cutting because the backlash, or the play between the lead screw and the nut in the machine table, is eliminated (Figure 1). Recently, however, Climb Milling
cern, especially in the case of steel forgings.
