The experimental results showed that the surface roughness of EDM machined mold cavity improved by 82% (from 4.23 μmRa to 0.76μmRa) within 90 minutes. Moreover, the parting surface roughness improved by 94.7% (from 1.l4μmRa to 0.06μmRa). We show that employing the abrasive jet polishing technique with wax-coated SIC particles, not only the mold surface roughness got a good improvement, but also significantly shorten the polishing time.
