The production process of a machine refers to the entire process of making a product from raw materials (or semi-finished products). For the production of machinery, including the transportation and preservation of raw materials, the preparation of production, the manufacture of blanks, the processing and heat treatment of parts, the assembly and commissioning of products, paints and packaging. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize production and guide production, and regard the production process as a production system with input and output.

In the production process, the process of changing the shape, size, position and properties of the production object to make it into a finished product or a semi-finished product is called a process. It is a major part of the production process. The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the mechanical processing process of the parts and the assembly process of the machine. Other processes are called auxiliary. Processes such as transportation, storage, power supply, equipment maintenance, etc. The process is composed of one or several sequential processes, and one process consists of several steps.

The process is the basic unit that makes up the machining process. The so-called process refers to the part of a process (or a group of workers) that is continuously completed on the same workpiece (or several workpieces at the same time) on one machine (or one work site). 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 continuously completed.

The step is that the processing surface is constant, the processing tool is constant, and the cutting amount is constant.

The cutting tool, also called the working stroke, is the step of processing the machining tool once on the machined surface.

To formulate the machining process, it is necessary to determine the order in which the workpiece passes through several processes and processes. Only the abbreviated 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 methods of each surface, determine the processing order of each surface, and the number of processes in the whole process. The process route is drafted in accordance with certain principles.
