Abstract

Chattering is a kind of self-excited vibration encountered in different machining processes such as milling and TURNING. This type of self-excited vibration rapidly develops after commencement and destabilizes the whole process. This phenomenon leads to, among other issues, increased noise, wavy surface finishes, discontinuous chips, and failure in the tool or machine parts. The depth of cut is the main parameter in the occurrence of CHATTERing in machining processes. Avoiding the critical depth of cut ensures the stability of the process. Process modeling is a way to obtain the critical depth of cut. The vibration-assisted TURNING process has many advantages and is of a different nature than the conventional machining. In this paper, the vibration-assisted TURNING process is modeled and numerically solved and the critical depth of cut is obtained. Validation of the results is performed using experimental data and comparison with conventional machining. In the vibration-assisted TURNING process, higher stability is obtained with lower ratios of cutting duration to the total vibration period.This ratio is directly proportional to vibration frequency and amplitude and is inversely proportional to the cutting speed.
