Basic knowledge of machining technology i. production process and production process of products refer to the whole process of transforming raw materials into finished products. The production process of mechanical products generally includes:
1. Preparation of production and technology, such as process design and design and manufacturing of special process equipment, preparation of production plan, preparation of production data, etc;
2. Manufacturing of blanks, such as casting, forging, stamping, etc;
3. Machining, cutting, heat treatment and surface treatment of parts;
4. Product assembly, such as general assembly, component assembly, commissioning inspection and paint, etc;
5. Production services such as the supply, transportation and storage of raw materials, purchased parts and tools;
The process of changing the shape, size, relative position and property of the production object in the production process to make it a finished product or semi-finished product is called process. For example, the manufacturing, machining, heat treatment and assembly of rough are all technological processes.
In the process of machining, if the shape, dimension and surface quality of the production object are directly changed by the method of machining, it is called machining process. Similarly, the process of assembling the processed parts into a machine to achieve the required assembly accuracy and obtain the predetermined technical performance is called the assembly process.
Machining process and assembly process are two main contents in the research of mechanical manufacturing technology.
2、 Composition of machining process
The machining process is composed of one or several sequential processes, which can be divided into several installation, working position, working step and cutting.
