在机械加工工艺文件中,施工过程卡是每个产品必需编制的.它为计划调度、计价,工艺工装设计,劳动工资等提供了技术依据.此卡也是工艺人员花费时间和精力最多的工艺文件之一.但目前国内大多数工厂仍沿用50年代的方法编制,既慢又不规范,使工艺文件管理长期处于较低水平.为此,我们经过长期的研究和比较,提出用网络图原理来编制.这种方法较简单、易掌握,适合单件小批或批量生产中使用,使施工过程卡易实现标准化和规范化,在此基础上有可能编制计算机软件,实现联网和无纸化管理,使工艺文件的编制和管理跨上一个新台阶.现将编制方法简述如下:
In the machining process documentation, the construction process card is required for each product. It provides technical basis for planning and scheduling, pricing, process tooling design, labor wages, etc. This card is also the process document that the craftsman spends the most time and energy. One of them, but most of the factories in China are still using the methods of the 1950s, which are both slow and non-standard, so that the process file management is at a relatively low level for a long time. Therefore, after long-term research and comparison, we propose to use the network diagram principle. Compilation. This method is relatively simple, easy to grasp, suitable for single-piece small batch or batch production, making the construction process card easy to achieve standardization and standardization, on this basis may be prepared computer software, networking and paperless management, The preparation and management of process documents has been stepped up to a new level. The preparation method is briefly described as follows:
