He CNC machining (computer numerical control) refers to the process of manufacturing a part by removing material with a cutting tool that is under automated control rather than manual control by a machinist.
This cutting tool can be held stationary, with the workpiece moving, or the tool can be rotated and moved toward a stationary piece of material. He CNC machining It is usually made with metals, but it can also be used with plastics and composites.
He CNC machining has revolutionized the manufacturing industry since it was first introduced in 1952 with the Cincinnati Milacron Hydrotel. Since then, advanced robotic systems have been incorporated into machines to dramatically improve productivity and ultimately reduce labor requirements for the component manufacturer.
CNC machining: an efficient and tailored solution
He CNC machining refers to a type of subtractive manufacturing that is designed to manufacture a part automatically, either by advancing a rotating cutting tool mounted on a spindle toward the work material or by mounting the raw material on a spindle and transferring it to a stationary tool. The main function of a spindle in a CNC machine is to provide rotational motion to allow material to be cut.
The first CNC machine was developed in 1952 by a team of researchers working at MIT (Massachusetts Institute of Technology). This advancement followed the development of the first NC (Numerical Control) machine in 1949. CNC machines were patented in 1958.
John T. Parsons was the first person to invent and build an NC (Numerical Control) machine. The NC machine was designed to work directly with a set of punch cards that tell the machine where to move. This concept laid the foundation for the further development of the CNC machine.
A team of researchers from MIT (Massachusetts Institute of Technology), led by JF Reintjes, developed the first prototype of a CNC milling machine. Richard Kregg then collaborated with MIT to develop the Cincinnati Milacron Hydrotel, the first commercially available CNC machine. Cincinnati Milacron became one of the first manufacturers of CNC machines.
The CNC machine was created to allow the machining of complex shapes that could not be manufactured with traditional manual milling techniques. He CNC machining allowed machining mathematically developed profiles that trace a complex non-linear curve, which would be difficult, if not impossible, to achieve with manual machining.
The objective of CNC machining is to produce accurate parts in a repeatable manner with as little human intervention as possible. This ultimately results in a lower cost per part while maintaining high levels of quality.
