When designing mechanical parts, it should not only meet the requirements of use, that is, it should have the required working ability, but also meet the production requirements, otherwise it may not be manufactured, or it may be possible to manufacture but it is very uneconomical to cost labor and materials. Under specific production conditions, if the designed mechanical parts are easy to process and the processing cost is very low, such parts are called good manufacturability. The basic requirements of the process are:(1) the selection of reasonable blank preparation methods in mechanical manufacturing are: direct use of profiles, casting, forging, stamping and welding. The choice of blank is related to the specific production technical conditions and generally depends on the production volume, material properties and processing possibilities. (2) The structure is simple and reasonable design of the structural shape of the parts, the warning is good to use simple surfaces (such as plane, cylindrical surface, spiral surface) and its combination, and at the same time, the number of processed surfaces and the processed area should be as small as possible. (3) Provide appropriate manufacturing accuracy and surface roughness. The processing cost of parts increases with the improvement of accuracy, especially in the case of high accuracy, this increase is extremely significant. Therefore, high accuracy should not be pursued without sufficient evidence. Similarly, the surface roughness of the parts should also be based on the actual needs of the mating surface, make appropriate provisions. In order to design parts with good craftsmanship, designers must combine with process technicians and learn from them. In addition, in the metal technology courses and manuals also provide some basic knowledge about the process, for reference.
