Abstract:   (5449 Views)
The vibration assisted turning has received intensive attentions due to its advantages such as reduced machining forces and surface roughness. Chattering is a type of self-excited vibrations, occurring in various machining processes. Chattering vibrations, when started, grow rapidly and destabilize the machining process. Moreover, chattering affects surface finish, reduces tool life, and even damages workpiece and machine tool. In this paper, a method is proposed to investigate chattering phenomenon in vibration turning and to predict stability boundaries. The method is in time domain and is solved by numerical methods. The effects of vibration frequency and cutting time ratio are examined. It is shown that frequency has negligible effect while cutting time ratio has the most influence.
