What is numerical control for?

Numerical control is the abbreviation of numerical control, which is an automatic method to program and control a certain working process with the help of numbers, characters or other symbols.

1, numerical control usually uses a special computer, the operation instructions are expressed in digital form, and the mechanical equipment works according to the predetermined program. NC (Numerical Control): stands for ancient and primitive numerical control technology. CNC (Computer Numerical Control): Computer Numerical Control Technology-New Edition, the preferred abbreviation form of numerical control.

2. Digital control is an automatic control technology developed in modern times. The national standard (GB8 129—87-87) is defined as "the method of controlling machine tool movement and its machining process with digital signals".

Extended data:

1. In NC machining, it is a pulse group that the NC device transmits motion instructions to the NC machine tool, and each pulse corresponds to the unit displacement of the machine tool.

2. Most high-end CNC systems can automatically select tools, generate process routes, calculate cutting depth and cutting speed, and realize cutting simulation through session automatic programming system, which greatly improves the efficiency of online programming and complex surface programming.

3. NC technology and equipment are the enabling technology and the most basic equipment for developing emerging high-tech industries and cutting-edge industries. Numerical control technology is widely used in information industry, bio-industry, aviation, aerospace and other national defense industries all over the world, in order to improve the manufacturing capacity and level, and improve the adaptability and competitiveness to the market.

4, CNC lathe, turning center, is a kind of high precision and high efficiency of automatic machine tools. It has a wide range of machining performance, and can process straight cylinder, inclined cylinder, arc and various threads.
