AbstractMachining of many polycrystalline shape memory alloys CoNiAl (SMA) has been considerably a new phenomenon. CoNiAl alloys should be made available for final use after being formed, without loss of their shape memory properties. In this study, the effect of cutting parameters on kerf width and dimension tolerance of the Co based Shape Memory Alloy (SMA) have been investigated on the Abrasive Water Jet (AWJ) machine. After the cutting process, kerf width of the samples were investigated. The experimental results showed that water pressure, traverse speed and abrasive flow rate have a great effect on kerf width and dimension tolerance.
