Typically, the feed dynamics of machine tools are limited to reduce excitations of machine structure oscillations. Consequently, the potential increase in productivity provided by electrical direct drives cannot be exploited. The novel approach of th

To reduce the excitation of structural oscillations machine tools' feed dynamics are usually limited. Thus, their productivity is restricted, especially for high dynamic processes with negligible process forces. The principle of Kinematically Coupled

Nowadays, feed axes are often equipped with multiple parallel-acting actuators in order to increase the dynamics of the machine tool. Also, additional actuators for active damping are widely used. Normally, the drives or actuators are controlled inde

Resistance spot welding is used as a high-productivity joining process for the increasing use of lightweight materials in industrial applications. The main challenge for the welding of aluminum alloys is the wear of the electrodes. Due to the natural

Vorschubachsen von Werkzeugmaschinen werden oft mit mehreren, parallel wirkenden Antrieben ausgestattet. Auch zusätzliche Aktoren für die aktive Schwingungsdämpfung kommen zunehmend zum Einsatz. Im Beitrag wird die modale Regelung für Werkzeugmas

This chapter presents a mechatronic system concept for highly productive and accurate machine tools. Using the example of an experimental machine called ‘MAX’, it will be demonstrated that the working precision of a machine can be increased whils

Gantry stages, which consist of two parallel acting servo drives, are commonly used in machine tools. One drawback of this concept is the crosstalk between both drives due to the structural coupling that can cause stability issues and therefore limit

Thermally induced deviations become the limiting factor for the precision of machine tools. Structure-based finite-element models of high resolution can estimate these deviations with high accuracy but have also a high computational effort. With mode
