| Popis: | These days’ composites are finding wide application in all fields of Engineering because of their better properties. Drilling is the most generally perceived machining operation performed on composites and the quality of drilled hole has an imperative bearing. This paper analyses the microscopic and SEM images of the specimen surface and explores the impact of various drilling parameters on the thrust force induced and the roughness of drilled hole surface in drilling Al/Sic/Mica hybrid composites. The tests were carried out on a Vertical machining centre utilizing LMT Onsrud Solid Carbide 8 Facet uncoated Drills of diameter 5mm, 7.5mm and 10mm. Response surface methodology is used to develop mathematical models to predict the drilling thrust force and the surface roughness of the drilled holes in terms of various drilling parameters. The drilling parameters considered for the analysis are spindle speed, feed rate and drilling tool diameter. The outcomes demonstrated that the created model can be viably utilized for the forecast of drilling force and surface roughness of the holes drilled in the hybrid composites considered. |
