1、 1 摘要 人们对机械加工方法的研究，经历了许多阶段，而由单作坊小批量生产到后 来的大批量生产则是一个质的飞跃。大批大量生产不仅大大的提高了生产效率、 节约了成本，而且还大大减少了资源的浪费，应该说这是一种比较完美的生产方 式了。然而，随着经济的高速发展，社会对机械产品需求多样化的趋势也越来越 明显，品种的多样化和大批大量生产出现了矛盾。成组技术的就是为了解决这一 矛盾而出现的。 本文以拨叉零件为例子， 从零件的编码开始介绍了拨叉零件的成组设计方法 和步骤，即运用 OPITZ 分类编码系统对零件进行编码，根据相似性要求对零件 分类成组，继而得到组内每个零件的工艺路线。本文以铣削平面该工序的成组

3、cy and reduced costs,but also greatly reduce the waste of resources.It should be said that this is an excellent way of the production.However,with rapid economic development and social needs of mechanical products diversification trend is becoming increasingly obvious.The diversity of species and a

4、large number of mass production of the emerfence of contradictions.Group Technology is to resolve the contradictions arise. Based Plectrum parts,for example,from the beginning of the coding parts of the rotary parts of the group design methods and steps,OPITZ that use of classification and coding system for coding parts,under similar requirements for spare parts classification group,and then imtegrated the various parts of the characteristics of the design of composite parts group.Of compos
