What is numerical control for?

Numerical control is a technology that uses digital information to control mechanical movement and machining process.

Numerical control technology is a technology that uses digital instructions composed of numbers, characters and symbols to realize the action control of one or more mechanical equipment. Usually control mechanical quantities such as position, angle and speed, as well as switching quantities related to the flow direction of mechanical energy. The appearance of numerical control depends on the appearance of data carrier and binary data operation.

At the end of 1908, the perforated metal foil interchangeable data carrier came out. At the end of 19, a control system with paper as data carrier and auxiliary functions was invented. 1938, Shannon carried out fast data operation and transmission at MIT, which laid the foundation of modern computer, including computer numerical control system. Numerical control technology is closely combined with machine tool control and developed.

Advantages of numerical control

Numerical control technology can realize fast and efficient manufacturing process, reduce production time and increase output. This technology enables operators to automatically perform repetitive tasks and make time for more complex operations. In addition, CNC machine tools can run continuously, which greatly improves the production capacity. Numerical control technology allows customized manufacturing, enabling manufacturers to produce parts according to specific customer requirements. CNC machine tools can also produce parts in small batches, which is an ideal choice for prototype design and product development.

Numerical control technology has completely changed the mechanical manufacturing process by realizing accuracy, high efficiency, universality and customization. Applying numerical control technology to automatic machinery manufacturing can bring many benefits, including improving productivity, reducing labor costs and improving product quality.
