Urgently seeking an introduction essay on automation, about 3000 words

With excitement, I came to Chongqing University, which really made me feel happy. Both the joy of the first touch of university life, but also a vision of a better future. I will never regret for choosing machinery, on the contrary, I will also feel proud, because machinery is a good profession, there is a good prospect. Besides, I like machinery very much and believe that I will have a little achievement in the future. To be honest, I knew very little about mechanics at the beginning, so I entered the first class of Introduction to Mechanical Engineering with enthusiasm. At the beginning, Prof. Chen Xiaoan took us to wander in the long river of mechanical history, all the way, let us roughly understand the development of the world's machinery, but also on the history of China's machinery has a relatively deeper understanding. Our forefathers created all the way to the mechanical splendor and from the first industrial revolution, China's machinery and the world mechanical derailment, backward! Look at the late people created mechanical products such as guide car, seismograph, etc., at that time but represents the most advanced level of machinery. Look at the design and working principle of the guide car, the creativity and production level of the superb y convinced me, and listen to Prof. Chen said that now has not been able to restore the guide car, but also let me sigh ah! Lament the super wisdom of the ancestors, lament the ancient machinery of our country advanced. So, a new generation of us can only not enhance self-confidence, and now strive to learn scientific and cultural knowledge, for the great rise of China and struggle! Look at today, although I am now a manufacturing country, but not a manufacturing powerhouse, and our manufacturing level with the world's developed countries such as the United States, Japan, compared to a large gap. Mainly in the backwardness of manufacturing technology and equipment, low-level productivity is a serious surplus of high-level productivity is seriously insufficient, product quality and technology is not high, technology development capability is not strong, basic components and basic technology is not pass, low labor productivity, science and technology technology is seriously insufficient, the ability of technological innovation is very weak, the industrial structure is not as reasonable as possible, the system can not adapt to the situation, such as the needs of the development of the situation. We recognize our disadvantages, but we are absolutely undiscouraged, we are still fighting spirit, confidence, change our disadvantages, so that China's machinery in quality and quantity are standing in the world of advanced manufacturing. Afterwards, Prof. Chen showed us some pictures and videos, which let us see the epitome of modern machinery manufacturing industry and research. Especially when I saw the automatic, flexible and methodical movement of the machine tool manipulators and cutters, I was rarely excited. Through reviewing the information, I learned that CNC technology refers to the use of digital quantities and characters to send commands to achieve automatic control of the technology it is the manufacturing industry to achieve automation, flexibilization and integration of the basis of production. I understand that the working principle of CNC machine tools: now the processing of the required pieces of information, that is, the arrow of the workpiece and the tool thought of trajectory dimensional parameters, the amount of stealing as well as a variety of auxiliary operations, such as processing information with the prescribed text and numbers and symbols to form a code, according to a certain format to write the program, and then the processing program is inputted to the CNC device, through the CNC device of the processing and arithmetic, according to the various axes of the mobile After processing and arithmetic operation of the CNC device, the driving circuit of each axis is sent to the driving circuit of each axis, after conversion and amplification, it is used to drive the servo motor, drive the movement of each axis, and carry out feedback control, so that the tool, the workpiece and the auxiliary devices can operate methodically in strict accordance with the order and trajectory parameters stipulated by the program, and thus process the required workpiece. This makes me y to my previous self is how ignorant and modern science and technology of the awe and desire, have the desire to have the power. The second class was always filled with humor and active atmosphere, enough to see Professor Zhang Genbao's gift of humor and higher than eight talents. Then he talked about some mechanical knowledge, and I was most impressed by the life cycle he talked about. Looking at that concise tree diagram of the life cycle, one can see its rich connotation. Starting from the demand and inspiration of the society, to the design, manufacturing, testing, operation, sales and maintenance, and finally to the death of this mechanical product and even to the recycling after the end of life, how much professional knowledge it contains! At that time, I imagined that in the future, I would collaborate with others to complete a mechanical product, and then experience the life cycle of our product, isn't this also enjoying life? It may look small or insignificant, but can you see the effort behind it and the wealth of knowledge it contains? The heart is again a burst of blood boiling ah! Later, Prof. Zhang talked about the development direction of modern machinery industry and his own research direction. Modern machinery towards giant, miniaturization, high speed, high load, high precision and green direction, he emphasized his research green direction. Indeed, since the development of industry in the last century, now the environmental problems are getting more and more serious, pollution is getting worse, our machinery is absolutely irrelevant. Moreover, now with the development of the world and the dramatic increase in population, the earth's various resources continue to decline, some resources have even been developed, the resource problem is a worldwide problem. Therefore, the machinery industry should do its part to meet the needs of the world, towards the direction of green development. In this way, there is a green concept, green ideas, green design, green manufacturing, green production and green processing and other new research directions. Personally, there seems to be another underlying force driving my interest and passion for green machinery and recycling. I think I would like to engage in research in the direction of greening in the future if possible. Then he mentioned the advanced manufacturing technology, which includes advanced manufacturing process technology and advanced manufacturing automation technology. The advanced manufacturing process technology contains special machining, ultra-precision machining, micromachining and ultra-high-speed cutting. And the advanced manufacturing automation technology has: numerical control technology, industrial robot, flexible manufacturing system, computer integrated manufacturing system, intelligent manufacturing system. Advanced manufacturing technology represents the frontier of modern machinery and is also our future research direction. The professors' introductions point us to our future, not bad for an introduction! Prof. Xie, whose research direction is mechanical fault diagnosis, really opened my eyes and brightened up my eyes. He talked about the importance of fault diagnosis. If the machinery compared to people, our Professor Xie is a doctor, he is for the machinery, "look, smell, ask, cut", the mechanical problems for prediction, diagnosis and treatment. In this way, production costs and waste of resources can be greatly reduced, and greatly improve the quality of products and production efficiency, we can be very graphic understanding of the importance of fault diagnosis. And he showed us some basics of mechanical fault diagnosis and its role with his own research and working experience. Sensors are used to collect data from running machines at regular intervals, and then analyzed by computers and human beings to eliminate interfering information, retain information related to mechanical performance, and then analyze vibrations and fluctuations of the machine to obtain the performance and working condition of the machine. This will be able to predict the machine failure, detect the failure of the specific ** set so as to carry out timely diagnosis and treatment. These are done in a very short period of time, greatly improving the efficiency and bringing great benefits to society. In the end he made some tips and guidance to our university studies. He said very firmly that the most important thing in college is not to get the best grades, but to form a set of effective problem-solving methods of our own. Yes, it is important to have a systematic approach! The road ahead will be much smoother if we do so. Under Prof. Xie's guidance, I more y appreciate the difference between college and high school, college is more important, richer, and more closely related to our future. I hope that four years from now I will also be able to develop a set of my own, effective and systematic approach to solving problems. I will try my best and I walk through the four years of college life with confidence. One class is more wonderful than another! It ended perfectly with Prof. Yan Ping. Prof. Yan introduced us to one system after another about machinery, and although the content was basically too difficult for us, it showed us the depth of machinery. But at the same time I recognized that our research in this area is not yet mature and is being strongly explored. It is evident that this is the frontier science of modern machinery and the research direction of our generation. Prof. Yan then introduced her institute to us, and from some of her introduction, we can understand that the institute is well equipped and has made many achievements. And she warmly welcomed us to have the opportunity to work as junior assistants in the institute in the future to enhance our research ability. I am a person who likes research since I was a child, so I would love to go to the institute to experience it when I have the chance in the future, so as to lay a foundation for my future research career (maybe). Recently I read "The Key to Wisdom - Qian Xuesen on Systems Science", and although I couldn't understand most of it, I still read it hard, and I learned some of the ideas of systems science from it. One of the systems engineering is the organization of management systems technology, he started from the whole, according to the overall goal of the needs of the system approach as the core and the integrated use of relevant scientific theories and methods, using the computer as a tool for system structure, environment and function analysis and synthesis, including system modeling, simulation, analysis, optimization, operation and evaluation, in order to seek the best or satisfactory system approach and put it into practice. Personally, I feel that a system that combines the concepts of system science and the characteristics of machinery itself is sure to be the best or satisfactory scientific system. After these four wonderful and vivid introductory classes of mechanical engineering, I have a deeper understanding of machinery and a brighter vision of my future. Therefore, I am determined to fill the ground, rich and rich to walk this precious four years of college.
