Performance and wear analysis of polycrystalline diamond
Polycrystalline diamond (PCD) tools have been widely used in industry because of its ultra-hardness and high abrasion resistance. Electrical discharge grinding (EDG) and conventional abrasive grinding are currently the two main processes to manufacture PCD tools. However, PCD tools fabricated by the two methods show Class 1.
