“Effect of varying process parameters on surface roughness in AWJ machine” Using Analysis of Variance (ANOVA)

Abstract

As abrasive water jet (AWJ) machine starts to be used in industry, getting high quality surface has become a
major requirement. The most significant characteristic of the abrasive water jet cutting technology is cold cutting, which
does not have a thermic effect on the material. Being a non-traditional machine, AWJ is holding several deficiencies,
which limits its extensive applications. One of the deficiencies is striation marks presented on AWJ cutting surface.
The objective of the our experimental investigation is to conduct research of the machining parameters impact
on surface roughness of the machined parts, and derive conclusions referring to the manner in which certain machining
parameters affect surface roughness.
