Climb Milling vs. Conventional Milling

May 05, 2017During Conventional Milling, the cutter tends to dig into the workpiece and may cause the part to be cut out of tolerance. However, though Climb Milling is the preferred way to machine parts, there are times when Conventional Milling is the necessary milling style. One such example is if your machine does not counteract backlash.
