In the present study, experimental investigations were conducted to find out the effect of abrasive water jet machining (AWJM) process parameters on the surface roughness (Ra) of white Makrana Marble. The approach was based on Taguchi’s method and analysis of variance (ANOVA) to optimize the AWJM process parameters for effective machining. Nozzle transverse speed, water pressure, and stand of distance were selected as the input parameters while the other was kept constant. It was found that the water pressure and nozzle transverse speed were significant control factors and the stand of distance was the insignificant control factor in controlling the surface roughness (Ra). تفاصيل المقالة
