Precision machining is the process of changing the size or performance of a workpiece by a mechanical device. It can be divided into cutting and pressure machining according to the difference in processing methods.
The production process of precision machining refers to the whole process of making products from raw materials (or semi-finished products). For machine production, it includes transportation and preservation of raw materials, preparation of production, manufacture of blanks, processing and heat treatment of parts, assembly, and commissioning of products, painting and packaging, etc. Modern enterprises use the principles and methods of system engineering to organize and guide production, and view the production process as a production system with inputs and outputs.
In the production process, any process that changes the shape, size, location and nature of the production object to make it a finished or semi-finished product is called a process. It is the main part of the production process. Processes can be divided into casting, forging, stamping, welding, machining, assembly and other processes, machinery manufacturing process generally refers to the sum of the mechanical processing process of parts and machine assembly process, other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc.. Processes are composed of one or several sequential processes, a process consists of a number of work steps.
