Because Titanium retains its hardness and strength at high temperatures, the cutting edge suffers from high forces and stresses, coupled with the high heat generated in the cutting zone, which means that work hardening is likely to occur, leading to certain problems Produced, in particular, is not conducive to follow-up cutting process. Therefore, the choice of the best indexable insert grades and troughs is key to the success of the process. Past history has proven that fine-grained, uncoated inserts are ideally suited for Titanium machining; nowadays, inserts with a PVD Titanium-coated blade offer significantly better performance.
