Abstract
Highly dynamic additional axes are an innovative approach for the enhancementof machine dynamics with growing workspace requirements. The slower movementof the large machine is superimposed by the much more dynamic additional one.For the control of the machine, these redundant axes poses a demanding task:The axes of the machines need to be coordinated in such a way that the dynamiccapabilities of the potential of the high-dynamics axes is used while allkinematic and dynamic restrictions are observed. An integration of these axesin the motion planning of a modern NC-control is commonly held very difficultmathematically as well as in terms of control technique. The approach that ispresented here leaves the motion planning untouched and takes action at theend of the generation of desired drive values. It fulfils, as will be shown,the dynamic and kinematic requirements.
