1. Friction stir welding process

Friction stir welding technology has a wide range of applications and is an early technology that emerged. Friction stir welding is the use of rapidly rotating welding tools to friction the original components, generate heat, locally plasticize the original components, and form dense solid phase welds through the extrusion of the welding tools. The friction stir welding process is widely used in the current production process, and there is rarely a phenomenon of excessive material consumption. At the same time, using this process for welding does not require high temperatures. Therefore, the actual operation is relatively simple and the application range is very wide. It has been widely applied not only in traditional manufacturing, but also in some emerging manufacturing industries [2].

2 Carbon dioxide gas shielded welding process

The carbon dioxide gas shielded welding process is a method of welding using carbon dioxide as the shielding gas. This welding process uses the arc as a heat source for welding during operation, and uses carbon dioxide gas for protection to achieve the separation of the arc and air. This can ensure the combustion of the arc and prevent harmful substances in the air from affecting the welding process. This welding process is convenient to apply and easy to operate, suitable for automatic welding and all-round welding. However, it should be noted that there should be no wind during the welding process, as it may affect the effectiveness of carbon dioxide gas protection. Therefore, this process is suitable for indoor operation.

3 Nano processing technology

The development of nano processing technology is a relatively important processing technology in the development of science and technology. With the development of nano processing technology, its application in mechanical production is increasingly expanding. This processing technology is a combination of modern information technology, modern mechanical processes, optics, and new materials. The emergence of nanomachining technology not only improves work efficiency in production, but also marks an important beginning for humans to start studying the micro world.

4 Micromechanical sensing technology

Micro machining technology is a technology that processes smaller components, and the core of micro machining technology is micro mechanical sensing technology. Micro mechanical sensing technology can reduce the usage space of product components, improve the utilization rate of product space, and reduce the energy consumption of electronic products. In the current economic market, this type of micro mechanical sensing technology has been applied in fields such as electronic products, intelligent communication products, and medical equipment. With the continuous development of the times and the progress of science and technology, there are higher requirements for the development of micro mechanical sensing technology. Modern micro machinery must not only change to sensor miniaturization, but also have very high levels of resolution, sensitivity, and data density.

5 CNC machine tools

At present, CNC machine tool processing technology is gradually becoming the core technology in high-tech. With the continuous development of mechanical processing technology, CNC machine tool processing technology has gradually achieved intelligence and automation in production. It is a relatively advanced CNC process and is widely used. The emergence of CNC machine tool technology can greatly liberate labor and greatly improve work efficiency. At the same time, CNC machine tools have the characteristics of high accuracy, good quality, and high flexibility. Compared with traditional machine tools, CNC machine tools can complete complex surface processing tasks that were previously impossible for machine tools, greatly improving production quality.
