What is the meaning of CNC

CNC (numerical control machine tool) is the abbreviation of computer numerical control machine tool (Computer numerical control), which is an automated machine tool controlled by a program. The control system can logically process the program with the control code or other symbolic instructions, through the computer will be decoded, so that the machine tool to perform the prescribed action, through the tool cutting blank material processing into semi-finished finished parts.

CNC programming is part of the CNC machining industry, which is divided into manual programming and computer (PC) programming. If only easy plane processing and regular angle (such as 90, 45, 30, 60 degrees) of the oblique angle processing, with manual programming can be. If it is for complex surface machining, we need to rely on a computer (PC).

Computer (PC) programming depends on a variety of programming software (such as Pro/E, UG, CAXA) and so on, this kind of software and mainly rely on (CAD design, CAM manufacturing, CAE analysis) of the principle of the preparation of the combination. Learning this type of software is the main thing is to learn to three-dimensional construction of the number of models, only after the construction of a good number of models can be specified according to the actual machining routes, and finally through the machining routes to generate CNC programs. This kind of books are generally only about the computer (PC) software operation. In the new bookstore or to sell computer (PC) software learning bookstore to buy!

Computer numerical control machine tool is a kind of automatic machine tool equipped with program control system. The control system is capable of logically processing a program with control codes or other symbolic instructions and decoding it so that the machine moves and processes parts. English abbreviation CNC, also known as CNC machine tools, CNC lathes, Hong Kong and Guangdong Pearl River Delta area known as computerized gong.

CNC machine tools are generally composed of the following parts:

1, the host, which is the main body of the CNC machine tool, including the machine body, column, spindle, feed mechanism and other mechanical components. It is used to complete a variety of mechanical components of cutting processing.

2, CNC device, is the core of the CNC machine tool, including hardware (printed circuit boards, CRT monitors, key boxes, paper tape reader, etc.) and the corresponding software, used to input digital parts program, and complete the storage of input information, data conversion, interpolation operations, as well as the realization of a variety of control functions.

3, the drive device, it is a CNC machine tool actuator drive components, including spindle drive unit, feed unit, spindle motor and feed motor. It is under the control of the CNC device through the electrical or electro-hydraulic servo system to realize the spindle and feed drive. When several feed linkage, it can complete the processing of positioning, straight line, plane curve and space curve.

4, auxiliary devices, refers to some of the necessary supporting components of the CNC machine tool to ensure that the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring and so on. It includes hydraulic and pneumatic devices, chip removal devices, exchange table, CNC rotary table and CNC indexing head, including tools and monitoring and detection devices.

5, programming and other ancillary equipment, which can be used to carry out the programming of parts outside the machine, storage and so on.
