Abstract

The periodic nanotexture was superposed to the micro-textured grooves on the side surface of the punch. These grooves with nanotextures were shaped to have parallel and vertical orientations to the punch stroke direction, respectively. A stack of five amorphous electrical steel sheets was punched out with these micro-/nano-textured punches. The process affected zone at the vicinity of the punched hole was analyzed by SEM (Scanning Electron Microscopy) and a three-dimensional profilometer. The punch surfaces were also observed by SEM to describe the debris particle adhesion on them. The dimensional change in each layer of the stack before and after perforation was measured to describe the punching behavior with the comparison to the punch diameter.

摘要

周期性纳米纹理叠加在冲头侧面的微纹理凹槽上。这些带有纳米纹理的凹槽分别被加工成与冲头行程方向平行和垂直的方向。用这些微/纳米纹理冲头冲压出一叠五片非晶电工钢片。通过扫描电子显微镜（SEM）和三维轮廓仪分析冲孔附近的加工影响区。还用SEM观察冲头表面，以描述碎片颗粒在其上的附着情况。测量堆叠各层在穿孔前后的尺寸变化，以描述冲孔行为并与冲头直径进行比较。
