Abstract

A problem has emerged during the end-milling of hardened steels: a high frequency chattering phenomenon. On the other hand, a laser Doppler vibrometer has recently been developed to observe such high frequency vibration phenomena. Therefore, we propose a new method of monitoring chattering in the end-milling of hardened steels using laser Doppler vibrometers. The chattering behaviors of the end-mill shank were measured by two laser Doppler vibrometers from the feed and radial directions at the same time during the end-milling of the hardened steel. The following conclusions were reached: (1) Two kinds of chatter vibrations were confirmed as vibration modes whose frequencies differed during high and low cutting speed conditions. (2) The chatter vibrations at the high cutting speeds clearly differed from regenerative chatter, which has only been researched so far, by accurate measurement of chatter vibration modes.
