Including spare parts map, blank map, fixture assembly drawings and folders mapping of specific parts, machining process and machining processes card preparation.the design of this course is an important aspect of the practice of teaching. Completed nternship in the production, completion of machinery manufacturing and chnological foundation and other professional courses conducted. The adoption of the curriculum design, will learn theory and practice of combining production, tempered his analysis, problem-solving abilities, in the process I am an independent analysis and solution of the manufacture of mechanical parts of the problem, design a machine for this fixture A typical technology equipment, improved structural design capability for future graduates to design their own future and will be engaged in the work of an adaptation training, thus laying a good foundation . 目 录 1.零件分析…………………………………………………..…1 1.1零件的工艺分析……………………… ……………...…1 1.1.1以?30mm右端面为粗基准加工表面……….……1 1.1.2以?60mm左端面为基准加工表面…………….…1 1.1.3以Φ30mm中心线为基准加工表面…………...…1 1.2零件加工的主要问题和工艺过程设计分析……….…1 2.工艺分析……………
