What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

The simplified radiator model is more suitable for engineering calculations

In the actual design of automobile radiators, it is necessary to comprehensively consider heat transfer performance, resistance performance, economy and reliability. The model simplification simplifies the heat dissipation belt with louvered fins into multiple rectangular parallelepiped porous media regions. Due to the thin wall and large area of ​​the radiator tube studied, the radiator tube wall is simplified into a double side wall surface of corresponding thickness to reduce the number of solid meshes and reduce the coupling heat transfer in the cold and hot sides of the radiator. Calculate the workload. The simplified radiator model is more suitable for engineering calculations. The creation and meshing of the watershed structure is used to complete the meshing of the radiator calculation model. After the simplified radiator core part and the air flow area structure are relatively regular, the hexahedral structured grid is generated by the division method.

The water chamber part of the radiator uses a division method. Setting of boundary conditions. Inlet boundary conditions: According to the control method of the entrance test conditions in the heat transfer wind tunnel test of the automobile radiator, the air inlet and the water inlet adopt the speed entrance, and the speed direction is perpendicular to the entrance plane. According to the entrance measured by the test The data is set for speed and temperature. Outlet boundary conditions: pressure outlet boundary conditions are used for both the water outlet and the air outlet. The static pressure and “backflow” conditions need to be defined on the pressure outlet boundary. The “backflow” condition is the boundary condition used when a backflow occurs at the pressure outlet boundary. Wall boundary conditions: Because all the walls of the studied radiator are static, there is no surface chemical reaction, and radiation is ignored, so this article mainly sets the thermodynamic boundary conditions on the wall. Because strict thermal insulation is carried out in the heat transfer wind tunnel test, it is assumed that the outer wall of the air channel and the outer wall of the water are adiabatic walls, that is, the heat flux is set to be. According to the simplification of the radiator model, the wall of the water pipe becomes a double-sided wall surface with corresponding wall thickness. Only by coupling the front and back sides in the calculation, the solver can directly use the flow field variables of the adjacent grid to calculate the wall surface. The heat exchange.
