   As a person engaged in machining, reasonable design of product machining tolerance is conducive to the processing and quality assurance of parts, machining tolerance and machining allowance is often misunderstood, resulting in the design of machining tolerance is unreasonable, can not meet the drawing requirements of parts, and eventually scrapped.The design of mechanical parts first from the assembly point of view, according to the matching of parts to give the corresponding tolerance standards, and parts in the machining enterprise, it should consider the processing process and surface treatment to design the corresponding processing tolerance. In the early part of the rough, the general tolerance is relatively large, to leave the margin prevail, in the finishing, should consider the type of surface treatment, according to the size of the surface treatment method to design the dimensional tolerance of the finishing, to meet the precision of the product after finishing, many experienced process engineers, often easy to finish in accordance with the requirements of customer drawings The dimensional tolerance control is carried out, and the dimensional influence brought by surface treatment is ignored, which eventually leads to the parts' tolerance cannot be guaranteed, repaired or scrapped.Machining tolerances must be combined with production processing technology and surface treatment to set, if it involves the assembly process, you should also consider the size of the assembly change, choose what kind of assembly method, different assembly
