Introduction to Milling Tools and Their Application
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

Chapter 17. Processing of Metal Powders
9 Mechanical comminution (pulverization) involves crushing (Fig. 17.6), milling in a ball mill, or grinding of brittle or less ductile metals into small particles. 9 A ball mill (Fig. 17.6b) is a machine with a rotating hollow cylinder partly filled with steel or white cast-iron balls.
Introduction to Machining: Milling Machine - Mercer University
•Work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, it's necessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with T-bolts, but only lightly so as to permit adjustment of the orientation of the vise.

Types of CNC Machining
While all 4-axis simultaneous milling machines can perform 3+1 axis milling, not all 3+1 axis mills can do 4-axis simultaneous. One needs to make sure of their machine's capabilities before trying to run a program it may not support. 4-AXIS SIMULTANEOUS These are the most common CNC machines produced commercially.
