工艺文件的制订是生产技术准备工作的一部分,它对确保产品质量、组织和管理生产、估算产品的成本等都具有指导性的作用。然而,同样一个零件在同样的工艺条件下,工艺过程的制订往往因人而易,这对组织和管理生产带来不便。另外,在制订相似零件的工艺时(尤其是多品种、小批量生产类型),工艺人员往往是进行重复劳动。而具 The preparation of a process document is part of the technical preparation of the production process, which has a guiding role in ensuring product quality, organizing and managing the production, and estimating the cost of the product. However, the same part in the same process conditions, the formulation of the process is often easy for the people, which is inconvenient for the organization and management of production. In addition, the process of developing similar parts of the process (especially the multi-species, small batch production type), process personnel are often engaged in duplication of work. And with
