INFLUENCE OF ABRASIVE WATER JET TURNING OPERATING PARAMETERS ON SURFACE ROUGHNESS OF ABS AND PLA 3D PRINTED PARTS MATERIALS

Abstract

In this study, PLA and ABS materials produced by 3D printing with 14 mm diameter and 300 mm length were processed by turning with abrasive water jet machining. The effect of processing parameters with abrasive water jet on the surface roughness was investigated. The processing parameters are nozzle feed rate (60-210 mm/min), abrasive flow rate (150-225 g/min), chuck turning speed (75, 125, 175 and 225 RPM) and nozzle distance (3, 5, 7 and 9 mm). Experimental studies have shown that the increase in nozzle feed rate (from 60 to 210 mm/min), abrasive flow rate (from 150 to 225 g/min) and nozzle distance (from 3 to 9 mm) results in average surface roughness values increased by 26%, 35% and 19%, respectively. It was concluded that the increase in the rotation speed of the mirror (from 75 RPM to 225 RPM) resulted in a 17% decrease.
