Disign and Fablication of Polycrystalline Diamond Tool for Drilling of Aluminum Silicon Carbide Metal Matrix Composite (1994)

When using tungsten carbide tools in face milling only 120 m (cutting length) could be made before flank wear reached 0.4 mm. PCD tools cut 3600 m with only 0.05 mm of flank wear. In these operations, changes in cutting speed (less than 5 m/s) did not significantlyeffect flank wear rate. However, the grain size of PCD tools was a key factor to diminish the tool wear. A PCD tool with 50mum grain size exhibited good wear resistance compare with the other these types of tools with different grain size.
