Today's topic is: 2021 Fortune Global 500 Sub-Industry List: Aerospace and Defense Original link: In this list, Forbes summarizes 13 companies whose main projects are aerospace and defense, 6 in China, 5 in the United States, and 2 in Europe (Airbus France and BAE Systems in the United Kingdom); There are also some industries that generally list a little later each year; A major source of information related to the aviation and defense sector is the annual Top 100 Defense List of Defense News; And the British "Brand Finance" (Brand Finance) released the "Biennial World's 25 Most Valuable Aerospace and Defense Brands" list (Aerospace & Defense 25 Biennial), Wait for the more professional Top 100 Defense to Companies 2021 around August 15, and I will continue to write the article; All the leaderboards are designed to reflect the competition, the current situation; extrapolation of subsequent changes; The logic behind is induction, comparison, prediction (time vertical axis, ranking horizontal axis, curve outlook) track upper and lower limits, etc; Analysis category: US-China, P5, BRICS and industrialized countries; Due to well-known reasons, after the founding of the Republic, the construction of the industrial system relied on Soviet aid (the time was too short), the times were turbulent, and it entered the stage of self-reliance (the time was long). On the basis of a thin belly and no knowledge, it completed the establishment of weapons with two bombs and one star, Later, it was in line with the international community (joining the United Nations, establishing diplomatic relations between China and the United States, disarmament, land contracting, reform and opening up, and entering the WTO), and made certain progress in the field of people's livelihood, as well as in the field of regular industry and commerce, and the goals of the four modernizations were partially realized; In the future, there will still be resistance and motivation for the rise of China (restoration of resurgence). Briefly expand the basic idea; 1. The dome of energy and environment. For example, according to the developed countries, especially the developed countries in the United States and Europe, the American lifestyle needs 5 times of energy and environment; the European lifestyle needs 3 times of energy and environment; 2. Due to the limitation of geography and times, the Asia we live in has a limited land and sea area, and its resource carrying capacity and population carrying capacity are all 3 to 5 times that of the United States and Europe. Factors such as geographical expansion, industry, and technology have certain latecomer disadvantages; 3. Looking at the future from the past, never looking at the past, looking at the future and the past from reality, we should all have the ability and confidence to do a good job in China and Asia; there is a long way to go, and we should constantly strive for self-improvement;

Four-axis machining center and its characteristics

2023-08-23

1. what is a four-axis machining center The four-axis machining center refers to the machining center corresponding to the fourth axis of the CNC machine tool. In the three-axis CNC machining center, a rotating axis is added, usually called the fourth axis. Machining center is mainly used for processing plane, groove, curved surface, is the fastest growing products in CNC machine tools, is also the most widely used machine tools, machining center for machining, mold, shipbuilding industry, automotive and parts, aerospace and other fields. Features of 2. four-axis machining center (1) Four-axis machining programming is complex and difficult. Because multi-axis machining is different from the three-axis, it is in addition to the three linear motion, there are 1 to 2 rotational motion involved, the formation of the synthetic motion of the spatial trajectory is very complex and abstract, generally difficult to imagine and understand. For example, in order to process the required space free-form surface, it is often necessary to use multiple coordinate transformations or complex tool axis pointing control methods, and at the same time consider the coordination of the movement of each axis to avoid interference and collision. Four-axis machining can improve production efficiency. Multi-axis CNC machining can simultaneously control the linkage of more than 4 coordinate axes, and combine the functions of CNC milling, CNC boring, CNC drilling, etc. After the workpiece is clamped at one time, the machining surface can be milled, bored, drilled and other multi-process processing, effectively avoiding the positioning error caused by multiple installations, shortening the production cycle and improving the machining accuracy. 3. The four-axis CNC machining center has the characteristics of high precision. In the process of four-axis machining, the workpiece can complete the processing of multiple surfaces after one clamping, and can also perform high-precision machining of complex spatial surfaces. Very suitable for processing auto parts, aircraft structural parts and other parts of the forming mold. 3. compared to three-axis machining four-axis advantages Disadvantages of three axis machining: 1. The tool length is too long, the tool cost is too high 2. Tool vibration leads to roughness problem 3. Process increase, multiple clamping 4. The tool is easy to break 5. Increased number of tools 6. Unqualified workpieces caused by over-cutting 7. Repeat the knife to produce cumulative tolerances. Four-axis advantages: 1. The tool has been greatly improved 2. The processing process shortens the clamping time 3. No fixture required 4. Improve surface quality 5. Extend tool life 6. Centralization of production 7. Effectively improve processing efficiency and production efficiency. Main Application Fields and Typical Parts of 4.
