An in-depth investigation of the machining performance of Ti1-Xalxn PVD coatings during high-speed machining of 316 stainless steel

PVD coatings are being intensively developed for cutting tools to increase the productivity of machining processes and enhance the quality of machined parts. The temperatures and pressures at the tool/chip interface are extremely high during high-speed machining of hard-to-cut materials. Such conditions drive the need for effective surface protection, which can be accomplished by the application of Ti-Al-N-based coatings. This study …
