Characterization of worn milling tool edges, tool mark inside spherical mitigation pit and the FDTD simulation models.

(a) The micro-milling tool with flaws at the cutting edge caused by wearing. (b) The tool marks inside repaired pit introduced by the flaws at the cutting edges. (c) The cross-section profile of the repaired pit with tool marks. The mitigation pit is roughly 280 μm wide and 20 μm deep, achieved using a 500 μm-radius milling tool. (d) Schematic of the FDTD models for ideal mitigation pit and mitigation pits with single and multiple tool marks.
