Design significance: the adoption of the curriculum design, will learn theory and practice of bining production, tempered his analysis of the problem, identify problems and problemsolving abilities, in the process I am an independent analysis and solution of the mechanical parts of the manufacturing process issues, Design a machine for this fixture typical of equipment, improve the structure of design capability, enhance the professional skills for future graduates to design their own future and will be engaged in the work of an adaptation training, thus laying a good foundation. In the design of adjustment of the mentality, know how to do things carefully, confidence, tempering the will to strengthen the self.目 錄序言……………………………………………………………1一、零件的工藝分析及生產(chǎn)類型的確定…………………… 2……………………………………………2 …
