Thermo-mechanical performance of a TiAlN-coated micro-drill: effect of cutting speed and point angle on tool wear, cutting forces, and surface integrity

Abstract Cobalt Chromium Molybdenum (CoCrMo) alloys are essential for biomedical applications. However, their high hardness and low thermal conductivity severely hinder machinability. In micro-drilling, a geometric trade-off typically exists, where smaller point angles improve pe...
