Working principle and advantages of CNC machining
CNC machining generally refers to CNC precision machining of accounting machines, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. It is a new processing skill, and its main task is to compile processing programs to convert the original craft operations into accounting machine programming. Of course, craft processing needs experience.
Operating principle of CNC machining:
When the CNC system is activated, the required processing standards are programmed into the software and assigned to the corresponding tools and machines, which perform the specified standard mission like robots.
In CNC programming, the code generator in digital system generally assumes that the mechanism is perfect. Although there is the 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 summaries called part programs.
Use the CNC machine tool to input the program through the punch card. In contrast, the program of the CNC machine tool is input into the accounting machine through the keypad. CNC programming is reserved in the memory of the accounting machine. The code itself is written and corrected by the programmer. Therefore, the CNC system provides a wider range of accounting skills. It is important that the CNC system is not static, because the update prompt can be added to the pre-existing program through the correction code, and the weldment can be processed.
Advantages of CNC machining:
1. Many of them reduce the number of tooling and do not need messy tooling to process parts with messy shapes. To change the shape and standard of parts, you only need to correct the part processing procedure, which is applicable to 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 multiple types 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 volume.
4. It can be used to process disordered surfaces that are difficult to be processed by conventional methods, and even some processing parts that cannot be investigated.
