Large-scale mechanical processing mainly refers to the whole process of making products from raw materials in the process of production. For machine production, it includes the transportation and preservation of raw materials, the preparation of production, the manufacture of blanks, processing and heat treatment of parts, assembly and commissioning of products, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize production and guide production, and regard the production process as a production system with input and output. In the process of production, large-scale mechanical processing changes the shape, size, position and properties of its production objects, so that it can become a finished or semi-finished product, which is called a technological process. It is the main part of the production process. The technological process can be divided into casting, forging, stamping, welding, machining, assembly and other technological processes, the mechanical manufacturing process generally refers to the sum of the mechanical processing process of parts and the assembly process of machines, and other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc. The technological process consists of one or several sequential processes, and one process consists of several steps. The process of large-scale machining is the basic unit that constitutes the machining process. The so-called process refers to a (Or a group)Workers, on a machine bed (Or a workplace), For the same workpiece (Or several workpieces at the same time)Which part of the technological process is continuously completed. The main feature of forming a process is that it does not change the processing object, equipment and operator, and the content of the process is a continuous process of formulating mechanical processing technology, it is necessary to determine how many processes the workpiece will go through and the sequence of the processes. Only the brief process of the main process name and its processing sequence is listed, which is called the process route. The formulation of the process route is to formulate the overall layout of the process. The main task is to select the processing method of each surface, determine the processing sequence of each surface, and the number of work orders in the whole process. The process route must follow certain principles.
