大连机械加工工艺流程：

1、是工件或者零件制造加工的办法，，，，，
，接纳机械加工的要领，，，，，
，直接改变毛坯的形状、尺寸和外貌质量等，，，，，
，使其成为零件的历程称为机械加工工艺历程。。。。。。

2、是在流程的基础上，，，，，
，改变生产工具的形状、尺寸、相对位置和性子等，，，，，
，使其成为制品或半制品，，，，，
，是每个办法，，，，，
，每个流程的详细说明，，，，，
，好比，，，，，
，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，，，，，
，每个办法就要有详细的数据。。。。。。

3、手艺职员凭证产品数目、装备条件和工人素质等情形，，，，，
，确定接纳的工艺历程，，，，，
，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.
