Influence of the Elastic Properties of Supply Drives on Their Dynamic Characteristics

摘要

The supply drives of numerically controlled machine tools with a screw-nut transmission may be described on the basis of models adequately reproducing the resonant phenomena in the position and speed control loops due to longitudinal and torsional vibrations of the structural elements. The influence of such phenomena on the stability and dynamics of the drive is considered, along with effective preventive measures.
