General CNC machining usually refers to CNC precision machining, CNC lathes, CNC milling machines, CNC boring and milling machines, 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. The following is a brief introduction to the working principle and advantages of CNC machining. Welcome to read it!

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 NC 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 NC machine is instructed to cut in multiple directions at the same time. The placement of tools in the CNC system consists of a series of input overviews called part programs.

Use the NC machine tool to input the program through the punch card. In contrast, the programs of CNC machine tools are input into the computer through the keypad. NC programming is retained in the computer memory. The code itself is written and edited by the programmer. Therefore, CNC system provides a wider range of computing power. It is important that the CNC system is never static, because the updated prompt can be added to the pre-existing program by modifying the code.

Advantages of CNC machining:

① The number of tooling is greatly reduced, and complex tooling is not required for machining 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 applicable to the development and transformation of new products.

② The processing quality is stable, the processing precision is high, and the repetition precision 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 amount.

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