Research on high speed cutting database technology (2)

4 Basic structure of high-speed cutting database
The basic functions of the high-speed cutting database are shown in Figure 1. Among them, the input items are the specific requirements put forward by the user according to their own needs, such as the workpiece and processing requirements reflect the material type of the workpiece, the external dimensions before processing, tolerances, etc.; the output is processed by the high-speed cutting database to the user's needs. The output results, such as the tool material and model item, are the type of tool material recommended by the database to the user, the grade, and so on.
Combining the existing metal cutting database structure and the development status of computer and database technology, we believe that the high-speed cutting database should adopt C/S structure, which has the functions of distributed storage and processing of data and good dynamics, and is easy to expand. At the same time, the high-speed cutting database should adopt the results of artificial intelligence technology, with good and practical reasoning function and prediction function, and provide effective auxiliary tools for the promotion and application of high-speed cutting technology.
The basic structure of the high-speed cutting database is shown in Figure 2. The high-speed cutting database is mainly composed of database, data source, data evaluation and verification system, application development system, network and communication interface, output and user.
Database part: The database consists of cutting data, knives, upper parts, machine tools, fixtures, models, machining examples, other data and other sub-libraries, including: 1 cutting data; cutting parameter library mainly stores cutting speed, cutting depth, Feed quantity, cutting property, type, cutting fluid and other data; 2 Tool: store tool material, shape, model, processing use, manufacturer and other data; 3 workpiece: store workpiece material, grade, shape, processing type, processing properties, etc. Data; 4 machine tools: storage machine model, technical parameters, manufacturer and other data; 5 fixtures: storage tooling and fixture type, use and other data; 6 model: storage cutting parameter model, optimization model, coefficient model, cutting force model, tool Durability model, etc.; 7 processing examples: storage processing instance data; 8 other data: storage user management, database management and other aspects of data.
Data source section: Sources of data used in high-speed cutting databases, including cutting parameters provided by factories, laboratories, and literature manuals, machine tools, tools, fixtures, materials, models, and more.
Data Evaluation Verification System Section: Verify data provided by the database or entered into the database.
Application development system part: Complete application functions such as data query, record, update, modification, deletion, optimization, transmission, case reasoning, processing effect prediction, database management, etc.
5 Conclusion
Researching and establishing a high-speed cutting database is a major and realistic issue facing the mechanical manufacturing industry. The high-speed cutting database is of great significance for the popularization and application of high-speed cutting technology. The optimized cutting amount recommended by the high-speed cutting database during high-speed machining can significantly improve the processing quality and production efficiency of the workpiece, and reduce the processing cost. The economic benefits of enterprises enhance the market competitiveness of products. For the entire metal cutting industry, the use of high-speed cutting database will greatly improve the level of cutting processing in the whole industry, and obtain huge economic benefits.
