What is cnc?

cnc means what, this we will often see a device inside the factory, the operation is also relatively complex, the following to give you a detailed introduction.

cnc generally refers to computer numerical control of machine tools, in accordance with the pre-programmed machining program, automatically processed parts.

CNC (a program-controlled automated machine tool) generally refers to computer numerically controlled machine tools. Computer numerical control machine tool is an automated machine tool equipped with a program control system. The control system is able to logically process the program with a control code or other symbolic instructions specified, and decode it, so that the machine tool action and processing parts. English abbreviation CNC, also known as CNC machine tools, CNC lathes, Hong Kong and Guangdong Pearl River Delta area known as computerized gong.

Computer numerical control is the use of a dedicated program can be stored on the computer to perform some or all of the basic digital control functions of the NC system. Early CNC system is composed of hardware circuits called hardware numerical control (Hard NC), after the 1970s, the hardware circuit components are gradually replaced by a dedicated computer called computer numerical control system, generally using a dedicated computer and interface circuits, can be realized by multiple CNC equipment action control. Therefore, nowadays, CNC is generally CNC (Computer Numerical Control), and rarely use the concept of NC.

Computer numerical control is generally also known as numerical control, to understand the computer numerical control should start from the understanding of numerical control. CNC is the abbreviation of digital control, CNC technology is the use of digital information on mechanical movement and machining process control method. In the early days there were two versions: NC (Numerical Control): represents the old version, the original numerical control technology. CNC (Computerized Numerical Control): computer numerical control technology - the new version, the preferred abbreviated form of numerical control. NC may be CNC, but CNC in no way refers to the old numerical control technology.

"CNC" is the abbreviation for Computerized Numerical Control. CNC machine tools are in accordance with the pre-programmed machining program, automatically processed parts. We put the parts of the machining process route, process parameters, tool trajectory, displacement, cutting parameters (spindle speed, feed, back eating amount, etc.) as well as auxiliary functions (tool change, spindle positive, negative, cutting fluid on, off, etc.), in accordance with the provisions of the CNC machine tool instruction code and program format is written into the processing program list, and then the contents of this program list is recorded in the control media (such as perforated paper tape, Magnetic tape, magnetic disk, magnetic bubble memory), and then input to the CNC machine tool CNC device, so as to command the machine tool processing parts.

Traditional machining are manually operated ordinary machine tool operations, processing by hand shaking the mechanical tool cutting metal, by eye with calipers and other tools to measure the accuracy of the product. Modern industry has long been the use of computerized digital control of machine tools for operations, CNC machine tools can be programmed in accordance with the technicians in advance automatically on any product and parts directly for processing. This is what we call "CNC machining". CNC machining is widely used in all mechanical processing in any field, but also the development trend of mold processing and important and necessary technical means.
