Dynamic excitation of any machine tool structure is based on natural frequency of the structure and corresponding mode shape. Initial work of the thesis presents a systematic procedure and details of the use of experimental analysis and finite element modal analysis technique for determining the structural dynamic response of end milling machine.The simplified experimental modal analysis of dif...

This paper presents the prediction of micro-milling forces using the finite element method (FE). An FE model of orthogonal micro-cutting with round cutting edge is developed. The cutting force coefficients are identified from a series of FE simulations at a range of cutting edge radii and chip loads. The identified cutting force coefficients are used to simulate micro-milling forces. The simula...
