5 Axis CNC Machining Centers

Besides the linear axes X, Y and Z, 5 Axis Machining Centers also move in two rotary axes, often identified as A and B axis. The rotary axes tilt the tool with respect to the part. Physically, it can be either the tool that tilts or the part that tilts. True 5 axis CNC machining uses these axes to smoothly follow a contoured surface. This type of machining has long been important in the aerospace industry, where machined parts follow the aerodynamic forms of aircraft. Some machines move the rotary axes only to position the tool or work outside of the cut. A machine capable of this “3+2” machining often can reach all of the machined features of the part in a single setup.
