CNC is also called CNC processing, which refers to processing using CNC machining tools. Because CNC processing is controlled by the computer after programming, CNC processing has the advantages of stable processing quality, high processing accuracy, high repeated accuracy, complex processing, and high processing efficiency. In the actual processing process, human factors and operating experience will largely affect the final processing quality. Below, let's take a look at the twelve valuable experience summarized by an old driver with ten years of CNC processing experience ...
1. How to divide the CNC processing process?
The division of CNC CNC processing process can generally be performed in the following methods:
1. The scaling of the tool concentration is to divide the process according to the tools used, and use the same knife 具 CNC to process all the parts that can be completed on the part. Use the second knife and the third to complete the other parts they can complete. This can reduce the number of knives, compress the air, and reduce unnecessary positioning errors.
2. For the processing parts of the processing site, there are many parts with a lot of CNC processing content. The processing can be divided into several parts according to its structural characteristics, such as internal shape, shape, curved or plane. Generally, processing planes, positioning planes, and then processing holes; first processing simple geometric shapes, and then processing complex geometric shapes; first processing of parts with lower processing accuracy, and then processing accuracy requirements.
3. The sequential method of rough and refined CNC processing method For parts that are prone to CNC processing deformation. Due to the deformation that may occur after rough processing, it needs to be carried out. separate. In summary, when dividing the process, we must depending on the structure and process of the parts, the function of the machine tool, the amount of parts of the parts CNC processing, the number of installations and the production organization of the unit flexibly grasp. It is also recommended to adopt the principle of concentration of the process or the principle of scattered processes. It should be determined according to the actual situation, but it must be reasonable.
What principles should be followed by the arrangement of CNC processing order?
The arrangement of the processing sequence should be considered according to the structure of the parts and the status of the roughness, as well as the needs of positioning and clamping. The focus is that the rigidity of the workpiece is not destroyed. The order should generally be carried out in the following principles:
1. The CNC processing of the upper process cannot affect the positioning and clamping of the launch process. Those who are interspersed with general machine tool processing processes must also be comprehensively considered.
2. Give the internal cavity processing processes of the internal cavity of the inner shape, and then perform the shape processing process.
3. It is best to connect to the same positioning, clamping method or the same knife CNC processing process to reduce the number of repeated positioning times, and the number of times and the number of times the sword is changed.
4. Multiple processes performed in the same installation should be arranged first that the rigidity of the workpiece is damaged.
