Significance of six chosen process factors - independent variables (traverse rate, abrasive mass flow rate, pressure, J/T abbreviation and feeding direction that influence the surface quality has been evaluated by factors experiment type 26. The surface quality has been evaluated by static quality characteristic average roughness Ra. The multiple nonlinear regression equation obtained from ANOVA gives the level quality Ra as a function of the treatment factors. Different factor significance has been found, which generated surface profile under defined conditions by abrasive waterjet. The regression equations obtained from ANOVA and multiple linear regressions give the level quality Ra as a function of the treatment factors.}, language = {en} }
