一、问题的提出我厂在1982年研制开发民品磁电机过程中,最初在50摩托车用磁电机系统中所有文件、产品图样均采用隶属编号,对单一产品装配而言,零部件的隶属关系,由编号可以一目了然。当开发50摩托车用磁电机第3种产品时,发现许多零部件可以互相借用,标准化人员及产品设计人员已经感到利用隶属编号很不方便,且意识到,随着产品开发的增多,相应 I. Problems raised During the development of civilian magneto motors in 1982, all the documents and product drawings in the 50-magnet motor system for motorcycles used the affiliation number. For single product assembly, the affiliation of parts and components , by the number can be clear at a glance. When developing the 3rd product for magneto motors used in 50 motorcycles, it was found that many parts could be borrowed from each other. Standardization personnel and product designers had already felt that it was inconvenient to use the affiliated number, and realized that with the increase in product development, corresponding
