Study on the modulation period influence on cutting force and temperature of TiN/TiSiN coated tools

Titanium has been wildly used in automobile industry. However, it is recognized as a typical material which is difficult to cut. Therefore, this work aims at the effect of modulation period number on the cutting force, temperature distribution and temperature variation. It can be concluded that the TiN/TiSiN coated tool with the modulation period number of 3 had the best performance at various cutting speed. This may provide a guidance for coating structure design.
