Stepover is the same thing, it refers to the amount of overlap there is between passes. 40% is the default which is good for most general pocketing and roughing passes (when carving 3D objects). When making finish passes, you would reduce this number to 10%, especially when using a 1/16″ ball nose end mill .

The torque speed characteristic of a typical ball mill is shown in Figure 1. On this curve there are three distinctive points of interest, which uniquely characterize the ball mill operation. Figure 1 a) The breakaway from rest is identified as the region on the graph requiring 40% to 70% of nominal torque from rest to approximately 20% speed.
Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and illustrated on these pages.
