General CNC machining generally refers to computer numerical control precision machining, numerical control machining lathe, numerical control machining milling machine, numerical control machining boring and milling machine, etc. It is a new processing technology. Its main work is to compile the processing program and convert the original manual work into computer programming. Manual processing certainly requires experience.

Working principle of CNC machining:

When the CNC system is activated, the required machining dimensions are programmed into the software and assigned to the corresponding tools and machines, which perform the specified dimension tasks like robots.

In numerical control programming, the code generator in the digital system usually assumes that the mechanism is perfect. Although there is a possibility of error, this possibility is greater when the CNC machine is instructed to cut in multiple directions at the same time. The placement of the tool in the CNC system consists of a series of input overviews called part programs.

Use the numerical control machine tool and input the program through the punch card. In contrast, the program of the numerical control machine tool is input into the computer through the keypad. Numerical control programming is retained in the computer memory. The code itself is written and edited by the programmer. Therefore, numerical control system provides more extensive computing power. It is important that the numerical control system is by no means static, because updated prompts can be added to pre-existing programs by modifying the code.

Advantages of CNC machining:

① Greatly reduce the number of tooling, and complex tooling is not required for processing parts with complex shapes. To change the shape and size of a part, it is only necessary to modify the part processing program, which is suitable for the development and transformation of new products.

② The processing quality is stable, the processing accuracy is high, and the repetition accuracy is high, which meets the requirements of aircraft processing.

③ In the case of multi variety and small batch production, the production efficiency is high, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of cutting quantity.

④ It can process complex profiles that are difficult to be processed by conventional methods, and even process some unobservable processing parts.
