[Abstract]:High-grade CNC machine tool is an important basic equipment to realize the modernization of manufacturing technology and equipment manufacturing industry. The weak design and manufacturing ability of high-grade CNC machine tool seriously affects the improvement of manufacturing level and innovation ability of our country. The configuration design of machine tool scheme is an important link in the design of high-grade CNC machine tool, which directly affects the performance of the machine tool. In this paper, the key technology of high-grade NC machine tool configuration scheme reconstruction is studied, and the prototype system of high-grade NC machine tool configuration scheme reconstruction is developed, which is verified by application cases. The organization structure of this paper is as follows: in the first chapter, the research status of high-grade NC machine tool scheme design and configuration reconstruction technology is introduced, the background, purpose and significance of this paper are expounded, and the main contents and organization structure of the paper are also given. In the second chapter, the technical framework of configuration scheme reconstruction of high-grade NC machine tools is given, and the process model of configuration scheme reconstruction is constructed. In the third chapter, the evaluation index of high-grade CNC machine tool is analyzed, and the grey relational analysis is used to evaluate and select the machine tool configuration scheme. The performance index weight allocation problem is transformed into a multi-objective optimization problem, and the Lagrangian optimization method is used to solve the weight problem. Based on the evaluation matrix of each machine tool configuration scheme, the grey correlation degree between the solutions of each machine tool scheme and the ideal scheme is calculated, and the solution which is closest to the ideal scheme is obtained by using the possibility theory to sort the schemes. In the fourth chapter, through dividing the configuration units of the machine tool configuration scheme, we construct the unit group and the refactoring cell library, study the mapping relationship between the configuration units, and give the interface distribution among the configuration units. Coding the machine tool configuration unit and constructing the coding sequence of the configuration scheme.

In the fifth chapter, the architecture of the prototype system of the configuration scheme of high-grade NC machine tool is described, and the function of the system module is introduced. Through the application case of high-grade NC machine tool configuration scheme reconstruction, the application verification of the high-grade NC machine tool configuration scheme reconstruction technology proposed in this paper is carried out. Chapter 6 summarizes the work and research results of this paper, and looks forward to the future development direction of machine tool configuration reconstruction technology.
