大連機械加工工藝流程：

1、是工件或者零件制造加工的步驟，采用機械加工的方法，直接改變毛坯的形狀、尺寸和表面質量等，使其成為零件的過程稱為機械加工工藝過程。

2、是在流程的基礎上，改變生產對象的形狀、尺寸、相對位置和性質等，使其成為成品或半成品，是每個步驟，每個流程的詳細說明，比如，上面說的，粗加工可能包括毛坯制造，打磨等等，精加工可能分為車，鉗工，銑床，等等，每個步驟就要有詳細的數據。

3、技術人員根據產品數量、設備條件和工人素質等情況，確定采用的工藝過程，并將有關內容寫成工藝文件，這種文件就稱工藝規程。

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.
