用英文翻译中文 机械制造工艺设计是机械专业

Mechanical manufacturing technology of mechanical engineering design is an important content in research, technology and machining technology disciplines mainly fixture design, strong practicality, requirement in the learning process should be closely production practice, it also has the very strong comprehensive, the graduation design topic is car QT - 24 drive technology design, the main content as follows:
Firstly, the analysis of main parts, parts of the role and is analyzed, and through the analysis technology of components can understand the basic situation, and parts of process analysis can know parts processing and surface processing requirements. According to the requirements of machining parts graph, determine the shape and size of blank.
The second step, the selection of base, process and benchmark crude benchmarks. According to choose good benchmark, and usually make two or more processes, through the comparison and analysis process scheme, then choose can make parts dimension accuracy and geometric shape, location accuracy requirements of reasonable technology such as a guarantee.
The third step, according to the process route has been selected, every step of cutting dosages and basic man-hour and choose appropriate machine and tools.
Through the above, the complete basic design.
