AI Technical Summary
Machining titanium materials is challenging due to their high strength, chemical reactivity, low thermal conductivity, and tendency to cause 'chatter', leading to reduced cutter life, poor surface finish, and safety hazards from long continuous chips.
A cutting tool with a superhard polycrystalline diamond (PCD) table, where the PCD exhibits a high density of at least 95 volume percent diamond, and is bonded without a substrate, with a metal-solvent catalyst like cobalt present in interstitial regions, enhancing the coercivity and thermal stability of the cutting tool.
The cutting tool achieves improved durability and performance in machining titanium, reducing chatter and improving surface finish, while also safely managing long continuous chips through enhanced chip breaking capabilities.
