Multi-Level Dynamics in Deep Milling of Flexible Workpiece

Abstract:

Chatter is the most obscuring phenomenon and significant amount of research has been documented regarding prediction, control and elimination of chatter. The present study has been undertaken in order to investigate the effects of multilevel dynamics in the dynamic stability prediction of deep end milling of the flexible parts. In the course of development of stability lobes diagram (SLD), input parameter of structure dynamics plays a vital role on the precision of SLD. In the present study CutPro is used to develop SLD for deep end milling of flexible workpiece after considering two cases of frequency response function (FRF) identification of flexible workpiece. It is shown that for deep end milling of flexible workpiece it is not enough to just identify the FRF of the workpiece only at one free end of the workpiece. To develop the exact and precise SLD it is necessary to identify the FRF of the flexible workpiece at more than one point along the axial depth depending upon how deep the workpiece is being milled.
