CNC milling is also called computer numerical controlled (CNC) machining. Where milling itself is a machining process similar to both drilling and cutting. In this way it is possible to achieve many of the operations performed by cutting and drilling machines at once. Like drilling, milling uses a rotating cylindrical cutting tool. However, the cutter in a milling machine moves along multiple axes. In this way it creates a variety of shapes, slots and holes. In addition, the work-piece often moves across the milling tool in different directions. This is unlike the single axis motion of a drill.
The milling machine.
Milling machines are the most widespread type of CNC machines. Typically, we group them by the number of axes on which they operate. These axis get the X and Y label. In other words they designate horizontal movement of the work-piece (forward-and-back and side-to-side on a flat plane). Z represents vertical, or up-and-down, movement, while W represents diagonal movement across a vertical plane. Most machines offer from 3 to 5 axes, providing performance along at least the X, Y and Z axes. Advanced machines, such as 5-axis milling centers, require CAM programming for optimal performance due to the incredibly complex geometries involved in the machining process. These machines are very useful because they are able to produce shapes that would be nearly impossible using manual machining methods. Usually milling machines also integrate a circuit with cutting fluid. This liquid cools the cutting tool and the work piece as it become extremely hot during machining.
CNC milling as a machining process.
Computer numeric controlled machining centers produce a wide range of components. Furthermore, tooling costs involved have continued to become more affordable. In general, large production runs requiring relatively simple designs are better served by other methods. Although CNC machining accommodates a wide range of manufacturing needs. CNC milling centers are ideal solutions to everything ranging from prototyping and short-run production of complex parts to the fabrication of unique pre-cision components.
