Abstract

Application of ultra-hard cutting tool materials such as polycrystalline diamond (PCD) is continuously expanding. However, shaping of PCD blanks is a long, labor-intensive and costly process. Wire electrical discharge machining (WEDM) has the potential to be an effective and economical technique for the production of tools from PCD blanks. This paper reports the effect of grain size of PCD, discharge frequency and discharge energy of WEDM on machining feed rate and quality of machined surfaces of PCD blanks. Surface roughness and notch depth (which is often observed at the diamond WC interface) were measured to study the cutting edge quality of the PCD blanks.
