Make Your Chips Fly with the CNC Explorer – EdwoodCrafting

Jul 18, 2020· WOC is often also referred to as STEPOVER or overlapping the cuts. The smaller the stepover the more finished the cut is generally to a point and depending on the geometry of the bit. A flat bottomed mill would not benefit from a small stepover but a ball nose would. The general rule of thumb for WOC is not to exceed 40% of the diameter.
