Abstract

In this study, we performed end-mill processing of a difficult-to-cut material (JIS SUS310 stainless steel) and observed it with high-performance infrared thermography. We discuss the relationship between the tool temperature and difference in number of teeth and tool diameter. The tool temperature distribution can be analyzed at each rotating tool position in the end-mill process from images, considering the relationship between the duration of each frame and the rotating speed of the end-mill tool. Moreover, we examined the validity by comparing the results of unsteady temperature analysis by the finite element method (FEM) and the measurement results.
