摘要：

The present study has been undertaken in order to investigate the stability behavior of the flexible parts milling after considering an improved milling cutter helix angle model in which the total cutting force was obtained by integrating the differential cutting forces along the in-cut-portion of the flute. Very small changes in the initial and final immersion positions of the cutter arc segment were envisaged, to reflect the actual cutting conditions. Further the multi-frequency solution of the model was established for the stability prediction. The comparison of the stability lobes of the proposed model and Altintas zero order and multi-frequency solution model showed that the stability lobes with the low helix angle tend to follow the Altintas multi-frequency model and with that of the high helix angle tend to follow the Altintas zero order model. The experimental results showed strong agreement with the proposed model simulation. (C) 2011 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of [PEEA 2011]
