ROBUST PROCESS PARAMETER DESIGN IN ABRASIVE WATER JET CUTTING OF KEVLAR COMPOSITES
Tauseef Uddin SIDDIQUI, Mukul SHUKLA
Abstract: Abrasive water jet (AWJ) is particularly useful for difficult-to-cut materials such as composites and ceramics in the recent past. However, proper and optimum cutting parameter selection is necessary for economic and efficient cutting with AWJ. In the present work, four important process parameters namely water jet pressure, abrasive flow rate, quality level and standoff distance were used to study their influence on kerf quality characteristics, namely, surface roughness and top kerf width during AWJ cutting of Kevlar-epoxy composites. The optimal setting of cutting parameters was determined using Taguchi’s robust design method. It is observed that the quality level and water jet pressure have more significant effect on surface roughness and top kerf width rather than abrasive flow rate and standoff distance.
Key words: abrasive water jet cutting, Kevlar composite, surface roughness, top kerf width, Taguchi method.
