Vibrations are limiting the productivity and the process quality of cutting machine tools. For the monitoring of these vibrations, often external sensors, such as acceleration sensors, are used. These external systems require additional cost and main

Machine hammer peening is a production technology for the surface finishing of metal parts. A hammer peening tool is utilized to smooth and harden the work piece surface by an incremental micro forming process. Due to the production requirements of a

A common approach for the experimentally estimation of modal parameters is the Experimental Modal Analysis (EMA). EMA takes place in the standstill of the machine, consequently neglecting effects that only occur during the cutting process. Alternativ

The dynamic behaviour of machine tools differs between standstill and process state. Operational modal analysis (OMA) makes possible to identify modal parameter under process conditions. In this paper, it is shown, how far the assumption of a time-in

There are differences in the dynamic behaviour of a machine tool between standstill and process because of preloads, process damping and gyroscopic moments. The standard method to characterize the dynamic behaviour, the experimental modal analysis (E

The effect of torsional vibrations on the dynamics of metal cutting processes is studied. An extended dynamic process model is presented, where the spindle angle and the time delay are dynamic variables resulting in delay differential equations with
