Like painting a square with a marker, we can use horizontal passes with our endmill. So, think of our case as creating a headless box inside an MDF sheet. Pocketing is when we remove some of the material. Let’s say we want to pocket a square on a flat surface like MDF. We measure stepover in terms of the percentage of the tool diameter. Likewise, the distance your CAM specifies to move your bit after each pass in an iterative toolpath (in XY plane) is the stepover size. In this case, you are using a 50% stepover. Or instead, you can only move your marker down half its width, so that half of your marker is repainting the first band. The difference between 50% stepover and 100% stepover in CNC. If you color your second band just touching the bottom edge of the first one, you are coloring with a 100% stepover, because you moved down 100% of your marker width. But where do you start your second strip after the first pass? You repeat this process until you have colored the whole square. Once you’ve colored the top strip layer, you move down one layer and color another strip. You would move your hand horizontally, coloring a strip from the top. Imagine you want to color a square on a piece of paper using a marker. ![]() So, how will you decide? What Is Stepover in CNC CAM? Using smaller layer heights gives you better resolution, but it also takes longer to print. ![]() This is similar to layer heights in 3D printing. If this tempts you to use a smaller stepover, remember that a smaller stepover also means a longer machining time.
