High-speed imaging is used to directly visualize various phenomena in material processing such as cutting, electric discharge machining, and laser machining. By using high energy X-rays, phenomena inside materials can be analyzed. In this study, the phenomena of metal drilling were observed using a high-speed imaging system with 100 keV X-rays at SPring-8. Various interesting movies were observed with sub-millisecond order time resolution. In this presentation, we will show the latest results of this research and explain the importance of X-ray high speed imaging in the fields of materials processing.
