波胆历史 工艺流程：
1、是工件或者零件制造加工的步骤，采用机械加工的方法，直接改变毛坯的形状、尺寸和表面质量等，使其成为零件的过程称为机械加工工艺过程。
2、是在流程的基础上，改变生产对象的形状、尺寸、相对位置和性质等，使其成为成品或半成品，是每个步骤，每个流程的详细说明，比如，上面说的，粗加工可能包括毛坯制造，打磨等等，精加工可能分为车，钳工，铣床，等等，每个步骤就要有详细的数据。
3、技术人员根据产品数量、设备条件和工人素质等情况，确定采用的工艺过程，并将有关内容写成工艺文件，这种文件就称工艺规程。
Dalian mechanical processing technology process:
1. The process of manufacturing and processing workpieces or parts, using mechanical processing methods to directly change the shape, size, and surface quality of the blank to make it a part, is called the mechanical processing technology process.
2. On the basis of the process, changing the shape, size, relative position, and properties of the production object to make it a finished or semi-finished product is a detailed description of each step and process. For example, as mentioned above, rough machining may include blank manufacturing, polishing, etc., while precision machining may be divided into lathe, fitter, milling machine, etc. Each step requires detailed data.
3. Technicians determine the adopted process based on the quantity of products, equipment conditions, and worker quality, and write relevant content into process documents, which are called process specifications.
