Wear behaviour of various CVD diamond thick film specifications during turning Ti-6Al-4V

Due to the specific mechanical and thermal properties of Ti-6Al-4V, such as its high heat resistance, the suitability of certain cutting materials is adversely affected. However, the high thermal conductivity and wear resistance of CVD diamond thick films provide the possibility for machining these materials. The present study investigates the wear behaviour of different CVD diamond thick film specifications at various cutting conditions. In particular, differences in the process forces of 53% due to the CVD diamond thick film specifications as well as deviations in tool stability due to process parameter dependent cracks or wear progress were observed.
