Investigation on the Influence of Process Parameters on Surface Roughness and Kerf Properties in Abrasive Water Jet Machining of Carbon Fibre Vinyl Ester Composite
Abrasive water jet machining is one of the most developed nontraditional machining process. It is generally used to cut difficult-to-cut materials like composites. The present work is focused on machining of carbon fibre vinyl ester composite with abrasive water jet machining. The influence of process parameters, namely, water pressure, traverse rate and standoff distance on surface roughness and kerf taper is studied. Design of experiments is done using Taguchi’s L16 orthogonal array. It is found that water pressure is the most influencing parameter followed by traverse rate. It is found that surface roughness and kerf taper decrease with increase in water pressure and decrease in traverse rate.
