The technological process of large-scale mechanical processing is the step of manufacturing and processing workpieces or parts, and mechanical processing method can be adopted during operation, the process of directly changing the shape, size and surface quality of the blank during operation to make it a part is called the machining process. For example, the machining process of an ordinary part is rough machining-Finishing-Assembly-Inspection-Packaging is a general process of processing. The main production process of large-scale mechanical processing is to change the shape, size, relative position and properties of the production object to make it a finished or semi-finished product. It is a detailed description of each step and each process, for example, as mentioned above, rough machining may include blank manufacturing, polishing, etc. Finishing may be divided into cars, fitters, milling machines, etc. Each step must have detailed data, for example, how much roughness should be achieved and how much tolerance should be achieved. In the process of large-scale mechanical processing, its technicians will determine the adopted technological process according to the quantity of products, equipment conditions and the quality of workers, and write the relevant contents into technological documents, this kind of document is called process procedure. This is more targeted. Each factory may be different because the actual situation is different. The process specification for large-scale mechanical processing is one of the process documents that stipulate the mechanical processing process and operation methods of parts. It is under specific production conditions, the more reasonable process and operation methods are written into process documents in accordance with the prescribed form, which are used to guide production after approval. The machining process specification generally includes the following contents: the technological route of workpiece processing, the specific content of each process, the equipment and technological equipment used, the inspection items and methods of workpieces, cutting parameters, time quota, etc. In the process of formulating technological procedures for large-scale mechanical processing, it is often necessary to adjust the contents that have been initially determined before, so as to improve economic benefits. In the process of implementing the process specification, unexpected situations may occur, such as changes in production conditions, introduction of new technologies and processes, application of new materials and advanced equipment, etc, all require timely revision and improvement of process regulations. The display and printing of curves, reports, etc. and the high reliability of system data.
