Experimental investigation and modeling micro-drilling operation of aerospace material

Abstract

In the present growing world of technology, the micro-machining process has demanding operation in various sectors like aerospace, oil, defense, automobile, biomedical science and many industries at micro and nano levels of manufacturing and designing. In various types of micro machining, micro-drilling is the part of solid tool based micro-machining operation. Generally micro-drilling is used to fabricate micro-holes in micro-products. In the present investigation convectional micro-drilling has been carried out in Aerospace material i.e. P.M.M.A.(Poly Methyl Meth-Acrylate). Here an endeavor has been made for finding the optimal conditions to the micro-drilling operation upon acrylic sheet of polymer. For the optimum condition for micro-drilling operation, various factors are to be considered and these factors are known as process control parameters. In this study, the cutting speed and feed rate will be taken as process parameters, and circularity error, drilling torque, thrust force and machining time has been measured. Finite Element Modeling will be carried out by using ABACUS software.
