Numerical and Experimental Investigation for Stability Lobes Prediction in Thin Wall Machining

A Finite Element Analysis (FEA) and Fourier transform approach to obtain frequency response function (FRF) is presented in this paper. The aim in this paper is to eliminate the need for the classical impact experimental approach used in extracting structureʹs FRF.The numerical and experimental FRFs have been used to obtain stable regions in machining of thin walled structures, which gives a good comparison. Examples are presented and compared with experimental results with a satisfactory agreement.
