金属微型零件的小型化趋势导致了对高精度生产方法的需求。主要的挑战是，例如，缩小尺寸的工具和足够的定位精度冲裁。从一种新的方法，工具的小型化和实现，本研究的目的是显示对过程误差的工具灵敏度的评估。蚀刻硅冲头用于冲切铜箔，其中爆发发生在切割边缘。因此，在冲裁过程中的工具应力进行了分析，通过有限元（FE）的方法在定义的定位和工艺误差的依赖性和评价有关的工具应力和剪切边缘质量。
The trend toward miniaturization of metallic microparts results in the need of high-precision production methods. Major challenges are, for example, downsizing of tools and adequate positioning accuracy within blanking. Starting from a novel approach for tool miniaturization and its realization, the aim of this study is showing the assessment of tool sensitivity against process errors. Etched silicon punches were used for blanking copper foils, where outbreaks occurred at the cutting edge. Hence, tool stresses during blanking were analyzed by finite element (FE) method in dependency of defined positioning and process errors and evaluated concerning tool stresses and sheared edge quality.
