Mechanical processing production process

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 production, parts processing and heat treatment, product installation, and debugging, painting and packaging. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to arrange and guide production, and regard the production process as a production system with inputs and outputs.


In the production process, the process of changing the shape, standard, location and nature of the production policy to make it a finished product or semi-finished product is called a technological process. It is the first part of the production process. The process can be divided into casting, casting, stamping, welding, machining, installation and other process processes. The mechanical production process generally refers to the sum of the machining process of the parts and the installation process of the machine. Other processes are called auxiliary processes. Process, such as transportation, storage, power supply, equipment repair, etc. The process is composed of one or several sequential processes, and a process consists of several steps.


The process is the fundamental unit that constitutes the process of mechanical processing. The so-called process refers to the part of the process that a worker (or a group of), on a machine tool (or a job address), for the same workpiece (or for several workpieces at the same time) is completed one after another. The primary feature of forming a process is that the processing policy, equipment and operators are not changed, and the content of the process is ended one after another


The process step is under the condition that the processing surface is unchanged, the processing thing is unchanged, and the cutting amount is unchanged.


The tool pass, also known as the operation stroke, is the process step where the processing thing is processed once on the processing surface.


To draw up the process of mechanical processing, it is necessary to recognize that the workpiece has to go through several processes and the sequence of processes, and only list the title of the primary process and the brief process of its processing sequence, which is called the process route.


The formulation of the process route is to draw up the overall layout of the process. The first task is to select the processing method of each surface, recognize the processing sequence of each surface, and the number of processes in the entire process. The drafting of the craft route must follow certain principles.
