Because the model is to do different open die processing and forming, there are many disadvantages, and the product design will bring some influence, so the future of the model needs to do some tests, one is processing inspection, the other is design inspection.

　　1. 處理檢查

　　1. Handling inspection

　　A.檢查外觀模型是否符合設計，表面處理過程是否與設計一致，整體效果是否達到預期效果。

　　A. check whether the appearance model conforms to the design, whether the surface treatment process is consistent with the design, and whether the overall effect reaches the expected effect.

　　B.檢查結構模型是否可以組裝，是否有干擾，是設計干擾還是模型處理干擾，模型是否與3D一致。

　　B. check whether the structural model can be assembled, whether there is interference, whether there is design interference or model processing interference, and whether the model is consistent with 3D.

　　C型號是否合理可控的設計中,通常標準公差在0.51.5的范圍內,產品公差越大,越大鈑金零件變化較大,所以你需要特別指出模型中描述,什么尺寸是關鍵部分,需要做的,是什么尺寸,需要控制,顯示清晰。

　　In the design of whether model C is reasonable and controllable, usually the standard tolerance is in the range of 0.5 to 1.5. The larger the product tolerance is, the greater the change of sheet metal parts is. Therefore, you need to specially point out what size is the key part, what needs to be done, what size needs to be controlled and displayed clearly in the model.

　　附件的數量是否有遺漏?不要在那個時候安裝它們。

　　Are the number of accessories missing? Do not install them at that time.

　　2. 設計檢查

　　2. Design inspection

　　A.外觀模型到手后，進行設計判斷，外形是否美觀，拆卸比例是否協調，表面處理是否合理等外觀檢查。

　　A. after the appearance model is in hand, conduct design judgment, appearance inspection such as whether the appearance is beautiful, whether the disassembly proportion is coordinated, and whether the surface treatment is reasonable.

　　B.結構模型到手后，需要確定裝配后是否存在結構設計缺陷，是模型加工造成的還是結構設計造成的。例如，卡環設計為0.4，實際裝配后非常松。然后有必要確定模型處理是否不到位，導致卡環減小，所以卡環很松，還是卡環臂力太長太弱，需要檢測。

　　B. after the structural model is in hand, it is necessary to determine whether there are structural design defects after assembly, whether caused by model processing or structural design. For example, the snap ring is designed to be 0.4, which is very loose after actual assembly. Then it is necessary to determine whether the model processing is not in place, resulting in the reduction of the snap ring, so the snap ring is very loose, or the strength of the snap ring is too long and weak, which needs to be detected.

　　C.對材料的厚度，以及板材的變形和強度進行測試。還應檢測和考慮鈑金件加工變形引起的裝配問題。是設計中沒有考慮加工變形導致的裝配問題，還是模型工廠加工導致的產品變形?

　　C. test the thickness of the material, as well as the deformation and strength of the plate. The assembly problems caused by the deformation of sheet metal parts should also be detected and considered. Is the assembly problem caused by machining deformation not considered in the design, or the product deformation caused by model factory machining?
