Cutting temperature plays an important role in micro-scale cutting process because the dimension of the micro-milling cutter is relatively small and the wear of micro-milling cutter is sensitive to temperature. Considering the sidewall of a groove is formed by main cutting edge of the tool, and the bottom of a groove is formed by tool tip and the edge on the end of the tool. Therefore, effects of tool nose corner radius and main cutting edge radius on cutting temperature in micro-milling process cannot be ignored. However, few studies have been conducted on this issue. The effects of tool nose corner radius and main cutting edge radius on cutting temperature is investigated. A three-dimensional micro-milling Inconel718 model is established by using the software DEFORM3D. And the influence of tool nose corner radius and main cutting edge radius on the size and distribution of cutting temperature are studied by numerical simulation, which is verified by experiments. The work provide reference for the control of the size and distribution of the cutting temperature during micro-milling process.
