Mechanical processing refers to the process of changing the external dimensions or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing.
The production process of the machine refers to the entire process of making products from raw materials (or semi-finished products). For machine production, it includes the transportation and preservation of raw materials, preparation for production, manufacturing of blanks, processing and heat treatment of parts, assembly and commissioning of products, painting and packaging. 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 production process, the process of changing the shape, size, position and nature of the production object to make it into a finished product or semi-finished product is called a 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, and the other processes are called auxiliary Processes, such as transportation, storage, power supply, equipment maintenance, etc. The process is composed of one or several sequentially arranged processes, and a process consists of several steps.
The process is the basic unit of the machining process. The so-called process refers to a part (or a group of) workers, on a machine tool (or a work place), for the same workpiece (or several workpieces at the same time) that part of the process is completed continuously. The main feature of a process is that it does not change the processing objects, equipment and operators, and the content of the process is completed continuously
The working step is under the condition that the processing surface is unchanged, the processing tool is unchanged, and the cutting amount is unchanged.
Walking tool is also called working stroke, and it is the working step completed by the processing tool once processing on the processing surface.
When formulating the machining process, it is necessary to determine the number of procedures and the order in which the workpiece will go through. Only a brief process of listing the name of the main procedure and its processing sequence is called the route.
The preparation 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 order of each surface, and the number of steps in the entire process. The preparation of technological routes must follow certain principles.
