• Use plastic lifting rollers (no steel rollers) for blanking dies.

  防止颗粒进入模具（小心清洁输送机和模具）。
• Minimize the formation of particles (also refer to measures during cutting).
  尽量减少颗粒的形成（另请参阅切割过程中的措施）。
• Tryout is more complex/good contact pattern to avoid indentations.
  试模是更复杂/良好的接触模式，以避免压痕。
• No surfaces treated by cavity type EDM (high roughness and surface damage), construct die in a different manner
  无腔体 EDM 处理的表面（高粗糙度和表面损伤），以不同的方式构建模具
• Wire EDM is permitted 允许电火花线切割
• Polishing the functional surfaces: see next section.
  抛光功能表面：参见下一节。
• Take increased deflection of the blank and part into account.
  考虑毛坯和零件的增加挠度。

1.1.2 High tendency to adhere to die material

• Remedy through coating the die:
  通过涂布模具进行补救：

1.1.3 Lower density 1.1.3 降低密度

• Gravity cannot be utilized to the same extent as it can with steel sheet metal; scrap must reliably slide away, larger chute angles; roller conveyors, etc.
  重力的利用程度不能与钢板金属相同;废料必须可靠地滑走，溜槽角度更大;滚筒输送机等
• Air circulation causes very small chips from cutting to disperse easily into the die; provide pressure compensation in the die; large openings in castings
  空气循环使非常小的切屑在切割时很容易分散到模具中;在模具中提供压力补偿;铸件中的大开口

1.1.4 Lower roughness 1.1.4 降低粗糙度

• Prevent slippage during feed.
  防止进料过程中打滑。

1.1.5 Non-magnetic 1.1.5 非磁性

• Blanks and scrap cannot be guided using magnetic rollers, vacuum-based systems, etc., must be used instead:
  不能使用磁辊、真空系统等引导的坯料和废料必须改用：

2. Methodological requirements:
2. 方法要求：

• Avoid cut-outs 避免切口
• Avoid formation of folds or waves when the blank holder closes and when the punch is applied.
  避免在压边关闭和施加冲头时形成褶皱或波浪。
• Maximum cutting angle ${15}^{\circ }$${15}^{\circ }$15^(@)15^{\circ}, otherwise use a slide element.
  最大切割角度 ${15}^{\circ }$${15}^{\circ }$15^(@)15^{\circ} ，否则使用滑动元件。
• Areas of components that will be folded or hemmed in post-forming operations should be stretched only slightly in the drawing stage so that they have sufficient elastic reserves in the following operations.
  在成型后操作中将被折叠或包边的部件区域应在拉伸阶段仅略微拉伸，以便它们在后续操作中具有足够的弹性储备。
• Take increased springback into account (e.g. it is twice as high for sheet metal material AIMg0.4Si1.2 as it is for CR3).
  考虑到增加的回弹（例如，钣金材料 AIMg0.4Si1.2 的回弹是 CR3 的两倍）。
