EFFECT OF ADDITIONAL FACTORS ON DIMENSIONAL ACCURACY AND SURFACE FINISH OF TURNED PARTS

摘要: This article reports the experimental and analytical results of an investigation additional factors that affect dimensional accuracy surface finish turned parts besides three major cutting parameters—cutting speed, feed rate, depth cut. The selected were cooling method, blank size, work material. A three-level, three-parameter experiment was planned using design-of-experiment methodology. levels independent input parameters were: for method—dry turning, flood minimum quantity lubrication turning; size—φ20, 40, 60 mm; material—aluminium 6061, mild steel 1030, alloy 4340. measured output two most widely used characteristics parts—diameter error circularity—and characteristic arithmetic average. analyzed applying methods: traditional analysis, Pareto ANOVA, Taguchi method. rev...
