Apr 04, 2016Ball Mill Step Over Calculator. If you are doing 3D surfacing with a ball mill you know about step over and the scallops it leaves. There is a diminishing return on reducing the step over value - making it smaller increases machining time without really improving the finish. Here is a good blog post discussing the sweet spot for step over.
