Chrome

(1) the method of selecting the reasonable mechanical manufacturing blank for rough selection is: direct use of the material, casting, forging, stamping, welding, etc.. The choice of blank is related to the technical conditions of production, which is generally determined by the volume of production, the performance of materials and the possibility of processing.

(2) the structure of a simple and reasonable structure of the part of the structure, the use of the most simple surface (such as plane, cylindrical surface, screw surface) and its combination, but also should be as far as possible to minimize the number of processing surface and processing area.

(3) the accuracy and precision of the machining cost of parts of the manufacturing accuracy and surface roughness of the parts are increased, especially in the case of higher precision. Therefore, in the absence of full basis, should not pursue high accuracy. In the same way, the surface roughness of parts should be made according to the actual needs of the surface, and make the appropriate regulations.

To design a good part of the process, the designer must be combined with the process and technical staff and be good at learning from them. In addition, it also provides some basic knowledge about the process in the course and the manual of metal technology, which can be used for reference.
