Milling Step-over Distance Calculator. In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used. The size of the step-over distance and the tool diameter will

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is

The lifters in this mill, as estimated from data reported in et al., (2011), reduce the effective mill volume by approximately 4.4%, the crash-stop load volume by 7.7% and the ball charge volume by 8.9% compared with assuming a smooth mill shell. The correction accounting for lifter volume described above should, therefore, be made whenever measuring load volume or mass, although noting
