Anonymous users2024-02-04At present, the downstream industries of machine tools - shipbuilding, construction machinery, aerospace, automobiles, railways, power equipment, wind power equipment, power equipment, refrigeration equipment and petrochemical equipment, etc., have been vigorously developed, so the development of the machine tool industry is facing the best opportunity. However, China's machine tools in terms of quality, reliability and stability are still a certain gap with the international level, mainly in the design method is backward, the design data is aging, long-term imitation of foreign products, the foundation is not solid enough, so it is difficult to develop high-end products, etc., in order to make the machine tool designers more diverse, more broad-minded, and promote the development of China's machine tool industry, we have two schools, one enterprise and three strong cooperation, organized the preparation of this "practical machine tool design manual".
With the progress of science and technology and the change of social needs, the design theory and manufacturing technology of machine tools are also constantly developing. The rapid progress of computer technology and analysis technology provides strong technical support for the development of machine tool design methods. Computer-aided design and computer-aided code-aided engineering have been applied at all stages of machine tool design.
The design theory and method of machine tool have transitioned from manual drawing to computer drawing, which has changed the traditional empirical design method, from qualitative design to quantitative rough design, from static and linear analysis to dynamic and nonlinear analysis, and from feasibility design to optimal design.
The development and application of numerical control technology has made major changes in the transmission and structure of the machine tool, and the servo drive system can easily realize the single-axis movement and multi-axis linkage of the machine tool, so as to save the complex mechanical transmission system design, and its structure and layout have also been greatly improved.
With the change of social demand, the rock burial in front of the rock. The demand for high-mix, low-volume production of high-mix, and low-volume production has led to the emergence of advanced manufacturing systems such as FMS. The machine is:
The core equipment of the FMS. In the early days, FMS can be said to be a "machine-based system" design, that is, to construct FMS according to the characteristics of existing machine tools, but the traditional design of machine tools (including CNC machine tools) does not take into account its role in FMS, so it restricts the development of FMS in terms of function. The development of FMS puts forward new requirements for machine tools, requiring machine tool design to develop in the direction of "system-based machine tool design", which should consider how it can better adapt to the requirements of advanced manufacturing systems such as FMS when designing machine tools, such as requiring time-space flexibility, and logistics affinity, etc., which puts forward new requirements for the methodology of machine tool design.
