5、程中，通过改变生产对象的形状、相互位置和性质等，使其成为成品或半成品的过程。机械制造的工艺过程一般包括零件的机械加工工艺过程和机器的装配工艺过程。机械加工工艺过程（以下简称加工过程）是指用机械加工的方法直接改变毛坯的形状、尺寸、相对位置和性质等使之成为合格零件的工艺过程。加工过程直接决定零件和机械产品的质量，对产品的成本和生产率都有较大影响，是整个工艺过程的重要组成部分。20/20装配就是把加工好的零件按一定的顺序和技术要求连接到一起，成为一部完整的机器（或产品），它必须可靠地实现机器（或产品）设计的功能。

6、机器的装配工作，一般包括：装配、调整、检验、试车等。它不仅是制造机器所必需的最后阶段，也是对机器的设计思想、零件的加工质量和机器装配质量的总检验。通过对加工工艺过程的设计，我们可以更有效的利用现有的资源设备，降低生产的成本，缩短加工时间，从而实现生产的最优化。关键词：工艺过程；机械加工工艺；装配工艺AbstractProcessisintheproductionprocess,theproductiontargetbychangingtheshape,locationandnatureofeachother
