Until now, there are two theories how this serrated chip formed, both argued with their evidence. One is the adiabatic shear theory, which suggests that serrated chips are caused by periodic thermoplastic shear instability ...

This paper concerns on drillability of Ti-6Al-2Sn-4Zr-6Mo (Ti6246) from the point view of thrust force (Fz) & torque (Mz) using a TiAlN CVD coated carbide tool. The condition of the material was varied with three ...
