In recent years, with the increase of new products and the increase of the complexity of parts, CNC machining has been paid more and more attention by enterprises with its strong advantages, and has become the decisive factor for manufacturing enterprises to win market competition.

However, most of the manufacturing enterprises CNC machining efficiency is low, CNC manufacturing capacity is insufficient. Therefore, it is of practical significance to study how to improve the level of numerical control manufacturing and the ability of numerical control processing through efficient numerical control processing technology, so as to enhance the comprehensive competitiveness of enterprises and improve the ability of sustainable development.

CNC machine tools are different from ordinary machine tools, and the methods of managing ordinary machine tools cannot be copied to CNC machine tools. According to the management practice of some users who used CNC machine tools earlier for many years, all units with more CNC machine tools have a relatively centralized management method, that is, the method of "professional management and centralized use. The process technology preparation is the responsibility of the factory process technology department, and the production management is unified and balanced by the tasks assigned by the factory. If possible, the production mode of computer integrated management can be adopted. By the computer CNC machine tool production required for a variety of operations and processing information management, the implementation of information sharing, in order to reduce production preparation time, optimize the logistics route, can effectively improve productivity. In production practice, the processing efficiency of CNC machine tools depends to a large extent on the ratio of cutting time to the working time of CNC milling machines. The greater the ratio, the higher the production efficiency.

Generally speaking, the methods to improve the processing efficiency of CNC machine tools are as follows. First, change the understanding of CNC technology. CNC technology is a comprehensive technology. In addition to CNC machine tools, there must be corresponding supporting technologies and personnel support, especially in CNC. In the process of machining, people play a decisive role. The technical capabilities of management personnel, engineering and technical personnel, engineering maintenance personnel and operators will affect the production efficiency of CNC machine tools. Second, formulate effective tool management measures, such as pre-adjusting the tool to reduce the installation and adjustment time of the tool on the machine tool, and manage the tool through the management system to reduce the errors caused by manual management. Third, due to the direct relationship between the selection of fixture and the installation time and measurement time of the workpiece, the management of fixture should be realized.

In my opinion, in order to improve the efficiency of numerical control processing, it is suggested to set up a numerical control workshop to integrate technicians, production personnel, equipment maintenance personnel and inspection personnel in the same department, which is convenient for unified arrangement and collaborative service in production. The organization includes workshop minister, chief numerical control engineer, production planning and scheduling, numerical control process programmer, tool tooling engineer, equipment maintenance personnel, inspection personnel, numerical control operator, warehouse keeper, etc.

The purpose of setting up a numerical control workshop is to centrally manage and move forward the production, expose the factors affecting the efficiency of numerical control processing to the early stage of production as much as possible, do enough preparatory work before production, maximize the proportion of cutting time in the working time of numerical control milling machines, and reduce the waiting time for downtime caused by waiting procedures, waiting for technical processing, waiting for maintenance of machine tools, waiting for measuring tools, waiting for inspection and other reasons.

The production process is as follows: the company's production management department issues production tasks → numerical control workshop → minister → chief numerical control engineer (mainly in terms of numerical control technology and quality), production planning and scheduling → numerical control process programmer, tool tooling engineer → numerical control operator → inspector → warehouse keeper, and the production is over. Any link can not be disconnected, otherwise it will inevitably affect the processing efficiency and delay the production cycle. The functions of the chief numerical control engineer: after receiving the task, coordinate the production planning and scheduling to organize the numerical control process programmer and the tool and tooling engineer to do a good job in technical digestion, programming, preparation of tools and tooling fixtures and form technical documents. The function of the tool tooling engineer: prepare the tooling and tools required in the early stage according to the technical requirements and procedures and install them on the corresponding tool handle while measuring the tool length value. Finally, the numerical control operator can start the machine tool to process parts quickly when he gets the task list to receive the parts, drawings, programs, tools and tooling, thus greatly reducing the waiting time for downtime and increasing the proportion of cutting time in the working time of the numerical control milling machine.

As long as the above factors that affect the efficiency of CNC machining are optimized or solved, the efficiency of CNC machining will inevitably be greatly improved.
