    Effect of tool angle in nanocutting of single crystal GaN using diamond cutter by Yongqiang WANG, Hao XIA, Zhihang HU, Shuaiyang ZHANG, Shaohui YIN

    Published 2025-06-01
    “…Crucially, two distinct diamond abrasive grains with differing morphologies are employed as cutting tools: rake angle of −70° and a flank angle of 10°; rake angle of −43° and a flank angle of 20°.This direct comparison allows for the experimental assessment of the impact of varying rake and flank angles on surface morphology, chip formation behavior, and subsurface damage extent, using techniques such as transmission electron microscopy (TEM) and optical microscopy for cross-sectional analysis.ResultsThe integrated simulation and experimental approach yields profound insights into the role of tool angles: Increasing the positive rake angle or reducing the magnitude of a negative rake angle is found to significantly enhance the shear-dominated material removal mechanism. …”
