In PCD tool manufacturing, a PCD disc is cut into inserts using wire electro-discharge machining (known as EDMing) or laser cutting in the manner. Then the tips are brazed into the pockets made in tool bodies, trimmed and finished using EDMing, laser cutting, or grinding (polishing).
As a result, polycrystalline diamond (PCD) is slowly becoming a material of choice for such applications. The chapter presents the major research advances in PCD as a tool material. The wear mechanism of PCD is discussed at macro- and micro levels.
