Investigation of a processing model based on abrasive erosion phenomenon for CFRP

复合材料，如CFRP，是很难切割的材料，但它们的比强度是有用的。钻孔工具通常用于产生1-2 mm直径的小孔，但是工具磨损较早发生，导致加工成本的问题。与其他加工方法相比，在先前的报告中显示，使用爆破可以有效地产生大量的小尺寸孔。然而，关于这种爆炸处理有许多未知的机制。在本报告中，我们从冲蚀磨损的角度研究了爆炸的材料去除机制，通过改变工作材料和加工条件，如介质和压力，考虑最合适的方法。

Composite materials, such as CFRP, are hard-to-cut materials but their specific strength is useful. Drill tools are usually used to generate small holes of 1-2 mm diameter, but tool abrasion occurs early, causing problems of processing costs. Comparing other processing methods, it was revealed in the previous report that it was possible to effectively generate large quantities of small size holes using blasting. However, there have been many unknown mechanisms about this blast processing. In the present report, we investigated the material-removing mechanisms of the blast from the viewpoint of the erosion abrasion, considering the most suitable method through changing work materials and processing conditions such as media and pressure.
