1.展开方式要合，要便利节省材料及加工性；2.合理选择间隙及包边方式，T=2.0以下问隙0.2，T=2-3问隙0.5，包边方式采用长边包短边(门板类)；3.合理考虑公差外形尺寸：负差走到底，正差走一半;孔形尺寸：正差走到底，负差走一半；4.毛刺方向；

1.展开方式要合，要便利节省材料及加工性；

2.合理选择间隙及包边方式，T=2.0以下问隙0.2，T=2-3问隙0.5，包边方式采用长边包短边(门板类)；

3.合理考虑公差外形尺寸：负差走到底，正差走一半;孔形尺寸：正差走到底，负差走一半；

4.毛刺方向；

5.抽牙、压铆、撕裂、冲凸点(包)，等位置方向，画出剖视图；

6.核对材质，板厚，以板厚公差；

7.特殊角度，折弯角内半径(一般R=0.5)要试折而定展开；

8.有易出错(相似不对称)的地方应提示；

9.尺寸较多的地方要加放大图；

10.需喷涂保护地方须表示。

钣金加工对钣金密度的要求

钣金加工对钣金密度的要求

可是高密度机架带来的好处是显而易见，至少可以获得较高的运算能力和可用度。另外一个挑战来自于成本(例如：烟雾报警器/平方英尺)，但是它并不会致使高密度产生明确的费用。此外，对较高密度给予预期的高水平监测将抵消上述不利因素。
