Multi-axis CNC milling is an advanced milling technique that utilizes a multi-axis CNC milling machine. 5-Axis CNC milling centers are the most popular choice for advanced manufacturing machine shops, which generally comprise three linear axes (X, Y, Z) and two rotary axes (any two of A, B, C), which the machinist can manipulate simultaneously. The figure below illustrates this configuration.
Multi-axis CNC milling is capable of machining high-precision parts with geometric features like spline curves, profiles, surfaces, and undercuts. It is a crucial role of demanding industries like aerospace, automotive, and medical devices, where non-prismatic parts and tight tolerances are common.
