Optimization of Abrasive Water Jet Machine Process Parameter for AL-6351 using Taguchi Method

Abstract

Abrasive Water jet (AWJ) Machining is a recent non-traditional machining
process. Major part of this technology is a very high-pressure beam of water and abrasives,
which is used for machining. Abrasive water jet cutting of material involves the effect of a
high pressure velocity jet of water with entrained abrasive particles on to material to be
cut. This technology is widely used in industry for cutting difficult-to-machine materials,
milling slots, polishing hard materials, cleaning contaminated surfaces, etc. In the present
study commercially three different materials AL-6351 is machined with the abrasive water
jet machine. Experimental investigations should conduct to assess the influences of
Abrasive water jet machining (AWJM) process parameter on surface roughness. The
approach is based on Taguchi’s method to optimize the AWJM process parameter for
effective machining. It was found the process parameters are stand-off-distance from the
work surface; work feed rate, jet pressure Abrasive type are effective to evaluate criteria of
the work surface roughness. The Experiment will be conducted at “SUNCORE
ENGINEERING INDIA” Manjusar G.I.D.C Vadodara. AL-6351 is select as work piece
material and will be machined under abrasive water jet machine model DWJ 2030-FB.The
effect of various parameters as Traverse Speed, Abrasive flow rate, and standoff distance will
be checked on output parameter like surface roughness measured by Surface Roughness
Tester TR100. The Taguchi method will be used for designing the experiment and optimum
result can be achieved through ANOVA and Compare it With Minitab 16 at the end.
