Abstract: An output-only modal analysis (OMA) approach is presented to obtain the direct frequency response function (FRF) at the tip of the tool in micromilling setups. White noise input is provided using acoustic excitation and ...

Abstract: The existing chatter stability prediction algorithms fail in lowspeed machining of difficult to cut alloys, unless process damping contributed by the tool flank face–finish surface contact is considered. This paper ...

Abstract: The efficiency of the finite strip method (FSM) in modeling the varying dynamics of shell-like structures during machining operations is investigated. The workpiece is modeled as a shallow, helicoidal, cantilevered shell, ...
