5 Axis Milling – During cutting, 3 Axis milling plus 2 rotary axis movements allow a CNC machine to move a tool on 5 different axes. The cutting tool has the ability to move across the X, Y, and Z axes, but rotates on A and B axes as well, allowing the machine to approach a workpiece from every direction possible. With the proper tools attached, 5 axis milling can cut tedious designs in steel, aluminum, granite, and even marble. Often times used with a CAM/CAD system package, this type of milling allows for the most intricate cutting possibilities in modern times.
