Investigation on glass/epoxy composite surfaces machined by abrasive water jet machining

Experimental investigations were conducted to assess the influence of abrasive water jet machining (AWJM) process parameters on surface roughness (Ra) of glass fibre reinforced epoxy composites. The approach was based on Taguchi's method and analysis of variance (ANOVA) to optimize the AWJM pro...
