The production process of mechanical parts processing

The production process of a machine refers to the entire process of making products from raw materials or semi-finished products. For machine production, it includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly, and debugging, painting and packaging. The content of the production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize and guide production, and regard the production process as a production system with inputs and outputs.

In the production process of machined parts, the process of changing the shape, size, position and nature of the production object to make it a finished or semi-finished product is called a technological process. It is the main 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 machining 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 technological process is composed of one or several sequential processes, and a process consists of several steps.

The process is the basic unit of the machining process. The so-called process refers to the part of the process that is continuously completed by one or a group of workers on a machine tool or at a work site for the same workpiece or for several workpieces at the same time. The main feature of forming a process is that the processing objects, equipment and operators are not changed, and the content of the process is completed continuously

The working step is under the condition that the machining surface is unchanged, the machining tool is the same, and the cutting amount is the same. The tool is also called the working stroke, which is the step that the machining tool completes once on the machining surface. To formulate the mechanical processing process, it is necessary to determine the number of processes and the sequence in which the workpiece will go through. Only a brief process with the name of the main process 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 processes in the entire process. The drafting of the process route must follow certain principles.
