Mechanical processing process generally includes: processing of the workpiece process route, the specific content of each process, the equipment and process equipment used, workpiece inspection items and inspection methods, cutting quantity, time quota, etc. Finishing technology refers to changing the shape, size, relative position and characteristics of products according to the production process. Each step is a process, and each process is described in detail. As mentioned above, roughing may include blank fabrication, grinding, etc., which can be divided into cars, pliers, milling machines, etc. Each step should have detailed data, such as the thickness of the grind and the allowable deviation.

The technicians in the fine parts processing workshop decide to adopt the process flow according to the quantity of products, the condition of equipment and the quality of workers, and write the relevant content into the process file, which is called the process procedure. This is more targeted. Depending on the actual situation, it may vary from plant to plant.

Generally speaking, the process flow is the program, each step is the detailed process parameters, the process is a factory according to the actual situation of the preparation of the special process.
