In recent years, with the rapid development of manufacturing industry and the widespread application of machining technology, research on cutting parameters has become increasingly important. In order to make the machining process more efficient and effective, an effective and feasible way is to establish a cutting data base so as to provide the basis for controlling the precision and consistency of machining. The paper explores the concept, basic principles, application characteristics and research progress of cutting data base.
1. Introduction
In machining, cutting is the most important link, which is directly related to the quality and economic benefits of parts. As an effective way of improving production efficiency and accuracy, the cutting parameter database has become a necessary part of machining technology. In the CNC machining of complex curved surfaces, large quantities of machining experiment data can be obtained at one time, and the cutting parameters such as depth of cut, feed rate and cutting speed can be adjusted according to the shape of the workpiece and the size of the tool. The data in the cutting database can be used to optimize the cutting parameters, further improve the machining performance and achieve the purpose of saving materials and labor.
2. Definition of Cutting Data Base
The cutting data base is based on the cutting mechanics and machining technology theory, combined with the actual machining conditions, input the specified material, cutting parameters, machining parameters and tooling information into the cutting data base. It can be used to study, analyze and forecast the cutting force, cutting temperature, cutting vibration, tool wear and chip forming during machining process in CNC machining.
3. Basic ideas and application characteristics
The basic idea of cutting data base is to input the cutting parameters and tool parameters of CNC machining into the cutting data base, select the most suitable machining plan for different workpieces and materials, reduce the trial-and-error time of the machining process, and realize the optimization of the machining process. In the machining process, the cutting data base can provide powerful references for processing capacity, tool selection, cutting parameter scheduling and machining quality control, so as to realize automatic control and warning of machining data in real time.
The cutting data base also has some features, such as the smaller amount of data, the convenience of data search, cutting process planning and optimization, the avoidance of errors, and the technique of real-time dynamic cutting analysis. The cutting data base provides basic information for CNC machining process and can also help to solve the problems such as cutting force vibrations and overloads.
4. Research Status
At present, domestic and foreign experts have conducted a large number of researches on cutting data base. But the existing researches are mainly to analyze the cutting force, cutting temperature, cutting vibration, tool wear and chip forming of cutting tools under different milled parts, cutting tools and cutting parameters to establish a numerical simulation model. However, the research of cutting data base is still in its infancy and faced with many problems, such as the selection of cutting parameters and the lack of multi-stage optimization. At the same time, it also has a certain development potential in material selection, cutting parameter and process optimization, tool selection, cutting process control and quality optimization, etc.
5. Conclusion
In summary, cutting data base is a new research direction which has important application prospects on the development of machining technology. With the development of cutting technology, the establishment of cutting data base can not only reduce the time for obtaining experimental data, but also provide CNC machining with optimized cutting parameters and tool parameters, as well as facilitate intelligent control, which can effectively improve production efficiency and reduce economic losses. In the future, more research will be carried out in the direction of cutting data base to make the machining process safer and more economical.
