IntroductionMachining aims to generate the shape of work-piece form a solid body，or to improve the tolerances and surface finish of a previously formed work-piece，by removing excess materials in the form of Machining is capable of creating geometric configurations，tolerances， and surface finishes often unobtainable by any other However， machining removes materials， which has already been paid for， in the form of relatively small particles that are more difficult to recycle and are in greater danger of becoming Therefore，developments often aim at reducing or-if at all possible-eliminating machining， especially in mass For these reasons， machining has lost some important markets， yet， at the same time， it has also been developing and especially having captured new markets with the application of numerical Some feel for the important of machining may be gained from the observation that in 1983 there were about 2 million metal-cutting machine tools in the unite states ( of which some 5% were numerically controlled ) and that labor and overhead costs amounted to $125 billion， or 3% of the GNP
Mechanical engineering is concerned with the power of a door production engineering Machinery industry is provided for the national economy， the basic industries will be equipped with the development of science and technology and produce Most important， that must be translated)Mechanical engineering related is the natural science and technology as the theoretical basis， combining with the production practice of technical experience， research and development， design， manufacture， installation， use and repair machinery theory and practical problems in the application of (this is also very important)Mechanical engineering related is the natural science and technology as the theoretical basis， combining with the production practice of technical experience， research and development， design， manufacture， installation， use and repair machinery theory and practical problems in the application of Modern society is mechanical manufacturing and service of five factors (people， capital， energy and materials and machines)， and one in energy and material The more important)My father is a 1984 and shandong college graduates， industrial and distribution to machinery factory When I was young I always see him in his factory work until he gets off work， then to have a strong interest in By my father in my later education， I learned that engineering is a need good combination of theory and practice， not only have the professional knowledge and rich theory have strong ability and practice ability， the knowledge to use perfect work to be My father once said to me， "the man must not only smart engineering， super " Since then， I have decided to study the mechanical engineering， the study of Now， after these days in shandong university study of mechanical engineering knowledge， I have a more profound Shandong university students to mechanical engineering education is in the way of education in shandong polytechnic university under the premise of the 21st century， with the new situation faced by a series of reforms， formed a unique way of Shandong university of mechanical engineering students can adapt society's demands， leading to social progress， and contribute to the The students， as well as mechanical engineering students all， not only to the teacher taught by the professional knowledge and rich practical courses， the special requirement to the engineering training center for In addition， in the year before the graduate school， students will also go to the factory organized practice， fully understand the actual situation， know how to correctly apply knowledge and strengthen their practice In addition， through years of understanding， and through the Internet search I understand that the engineering education in China and foreign born of engineering education still has many different Although these are different， but it is different countries have different conditions of the Each university in with the international standard， according to their country's national education plans to determine the specific， cultivate true for At this point， shandong university will do very well， mechanical professional teachers to teach basic theoretical knowledge and teach the most advanced knowledge of China， and according to the specific conditions of college students is most suitable for mountain arrangement plan， make mountains adequately， comprehensive university， so that they can contribute to the motherland after
