Some common knowledge about CNC machining

With the rapid development of modern aviation manufacturing industry, CNC machining technology has become one of the key technologies in aircraft manufacturing. The advancement of CNC machining technology has changed the concept of aircraft design, and the design of parts is becoming increasingly integrated and complex. Meanwhile, the change in design concepts has also brought new challenges to CNC machining technology. How to complete CNC machining of large parts with high quality, efficiency, and low cost has become a difficult problem that needs to be overcome.

The history of aviation manufacturing abroad is very long, especially the design and manufacturing technology of large and complex aircraft structures is very mature. In recent years, with the development of various civil and military aircraft in China, major aviation enterprises have accumulated a wealth of technical experience in aviation CNC machining technology, solved a series of key technical problems, and initially formed key technological advantages represented by the manufacturing of large and complex aircraft structures. However, with the launch of China's large-scale aircraft projects, the CNC machining technology of aviation components will face greater challenges. Therefore, we still need to conduct in-depth research in the field of CNC machining technology to narrow the gap with Western countries.

The use of CNC machine tools not only requires the careful use of operators, but also relies on scientific management. A sound management system and scientific production mode are effective means to improve production efficiency.

1. Establish a sound management system, effectively control and supervise the work of personnel related to CNC machine tools, and control the entire process of machine tool operation and operation.

2. Strengthen the training of technical personnel and technical worker management personnel. Training in CNC machining is always a long-term task and a continuous process of improvement. By training technicians, we can develop more simplified CNC machining processes, simplify programs, and shorten processing time. Technical workers can improve their operational skills; Managers can better understand the characteristics and process control of CNC equipment, and implement management with modern production management concepts.

3. Scientific organization of production. Improve downtime and production capacity imbalance, increase the operating rate of CNC machine tools, arrange production rhythm reasonably, and allocate production tasks reasonably. By utilizing the similarity of parts processing, classify the processed parts and make reasonable arrangements in process planning, production planning, and scheduling to improve the balance of equipment production capacity. A scientific production batch will greatly reduce the proportion of machine tool adjustment time and tooling preparation time, and can improve batch efficiency.

In order to fully realize the value of CNC machine tools, operators need to correctly grasp the operating principles of CNC machine tools. Operate the machine tool correctly according to the operating procedures; Process parts according to process and program requirements; Before processing, coordinate the dimensions of parts, tools, pressure plates, etc. Avoid interference and collision; Improve technical quality and reduce non machining time such as tool installation and alignment; Properly maintain various accessories to ensure their accuracy and reliability.

The application of CNC machine tools is becoming increasingly widespread, and how to "manage, use, and maintain" CNC machine tools has become an important issue that urgently needs to be solved. The use of CNC machine tools is not just a simple device, but a highly specialized application project. Only through scientific management, full understanding of the characteristics of CNC machine tools, and coordinating the balance of various production processes, can their economic benefits be fully realized.
