Experimental Investigations on Machinability of Aluminium6063 Alloy by Abrasive Water Jet Machining
Guttikonda Venkata Mahesh,  Goteti Chaitanya
The abrasive water jet machine has gained popularity over other non-conventional machining methods due to the absence of heat affected zone, hazardous gases and ability to cut in any direction without the requirement of secondary processing methods. This is also a productive and efficient alternative to the traditional machining methods. In the present work, the influence of abrasive water jet machining (AWJM) parameters such as water-jet pressure, Feed rate, abrasive flow rate and stand-off distance (SOD) on measured responses such as material removal rate (MRR), Surface roughness (SR) are studied. Experiments were conducted based on Taguchi’s L9 orthogonal arrays. Due to the sum of degrees of freedom of the four parameters was equal to the total degree of freedom, a Zero error case was raised. So, to proceed further calculations, the factors having least contributions were pooled to get the pooled ANOVA and to check the significance. The results showed that Feed rate was having the most significant effect on Material removal rate (MRR) among the four factors and for the surface roughness Abrasive flow rate was the most significant.
