| Research Abstract |
As a method of processing cemented carbide, wire electrical discharge machining(WEDM) is generally used. However, typical surface defects, such as cracks, microcraters and recast layer, lead to a decreased surface integrity. Thus, an on-the-machine surface modification technology in WEDM, for the complete elimination of surface defects, was developed in this study. As a result, the surface defects generated by WEDM could be completely eliminated by incorporating SI-cut into WEDM. Thus, this surface modification technology is effective for finishing cemented carbide machined by WEDM.
