Cnc Manufacturing Wiki

A computer numerical control cnc router is a computer controlled cutting machine related to the hand held router used for cutting various hard materials such as wood composites aluminium steel plastics glass and foamscnc routers can perform the tasks of many carpentry shop machines such as the panel saw the spindle moulder and the boring machine. Cnc automation also allows for more flexibility in the way parts are held in the manufacturing process and the time required changing the machine to produce different components.

Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material by water jet cutting or by laser cutting.

Cnc manufacturing wiki. Cnc machining refers to the cnc machine tools for processing a part of the process cnc machine tool processing and traditional machine tool processing procedures are generally the same but also has undergone significant changes. Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material removal process. Numerical control also computer numerical control and commonly called cnc is the automated control of machining tools drills boring tools lathes and 3d printers by means of a computera cnc machine processes a piece of material metal plastic wood ceramic or composite to meet specifications by following a coded programmed instruction and without a manual operator. The processes that have this common theme controlled material removal are today collectively known as subtractive manufacturing in distinction from processes of controlled material addition which are known as additive manufacturing. The original class of machine tools for milling was the milling machine often called a mill. Milling machines augmented by automatic tool changers tool magazines or carousels cnc capability coolant systems and enclosures. Cnc is also commonly used with many other types of machining besides turning when turning the workpiece a piece of relatively rigid material such as wood metal plastic or stone is rotated and a cutting tool is traversed along 1 2 or 3 axes of motion to produce precise diameters and depths. After the advent of computer numerical control cnc in the 1960s milling machines evolved into machining centers. Cnc automation reduced the frequency of errors and provided cnc operators with time to perform additional tasks. This type of machining was originally performed mechanically on large complex machines.
