Abstract
This study was performed to investigate the effects of injection speed and polishing time on the machined surface properties of carbide material in the blast polishing process. The results indicated that when injection speed was 21.4 m/s or more, the surface roughness value decreased quickly with increases in polishing time, and was almost saturated at a certain polishing time. The saturated surface roughness value of each injection speed decreased with increasing injection speed. The surface roughness value reached saturation more quickly at higher injection speeds.
