Original Abstract

The key role in the development of machine tools is played by an analysis of self-exited vibration during machining, which has a crucial effect on the whole process. For a successful development of a new machine tool, analysing this problem is necessary. However, the most common methods are limited to a linear orthogonal system, with a lack of control system influence. This paper describes a time-domain model of chatter stability during machining. The main body of this twin was a regenerative principle model which connected the spindle and the slide models. The spindle model contained vector control of an induction motor and a torsion elastic shaft model. The slide was modelled in MSC Adams and co-simulated with the rest of the model in Matlab-Simulink. The twin was validated by experimental measurements. In the future the model will be used for artificial control system development. For more a precise analysis, the virtual twin could be extended by adding more degrees of freedom.
