Burr height and hole diameter error minimization in drilling of AL6063/15%/SiC composites using HSS step drills

다국어 초록 (Multilingual Abstract)

In drilling process, burr plays an important role on the quality parts. It is necessary to minimize the burr height. This paper presents theeffect of CNC drilling process parameters like cutting speed, feed rate, step angle and cutting environment on burr height and hole diametererror of Al6063/15%/SiC composites. The composites are fabricated using mechanical stir casting. An experimental study on compositeswas conducted using three HSS drills. The Taguchi design of experiments and analysis of variance (ANOVA) are used to optimizethe response for Al6063/15%/SiC composites. The results revealed that the quality of the holes can be improved by proper selection ofcutting process parameters. SEM analysis and XRD analysis are also carried for composite, drilled surface and drill bits. These analysisprovide the good agreement with the effect of cutting parameters on burr height and hole diameter error.
