Surface Texture Manufacturing Techniques and Tribological Effect of Surface Texturing on Cutting Tool Performance: A Review (2016, unknown): “A variety of dimple shapes, including triangular, circular, square, diamond-shaped, and hexagonal, were numerically studied by Siripuram et al.173 The maximum amount of side leakage was reduced by triangular shapes.”
