Influence of Different Abrasives Mixtures on Abrasive Water Jet Drilling of Die Steel

Abrasive Water Jet Machining (AWJM) is a non-traditional machining process used for cutting an extensive range of materials by means of a mixture of water and an abrasive substance. The present study describes the effect of abrasive materials and stand-off distance on AWJ drilling of die steel. Different abrasives namely Silicon Carbide, Garnet, and abrasive mixtures of silicon carbide and garnet in the ratio of (60:40) were used in this study. The Output responses, namely cylindricity, circularity, and surface roughness of the drilled surfaces were analyzed. The experimental results showed that the mixture of the different abrasives increases the cutting ability of AWJ performance as compared to single type abrasives, namely, garnet or Silicon Carbide in die steel.
