Coupled controller-mechanics simulation

Today's drives in machine tools and robots place increasing demands on the supporting mechanics. A perfect interaction between control and mechanics is the prerequisite for a powerful machine.

With the help of the coupled controller-mechanics simulation we can directly evaluate and improve the machining accuracy. The result is also illustrative for laymen, because we measure the deviation in µm.

At this point we would like to explain the differences between virtual commissioning and the coupled controller-mechanics simulation:

• Virtual commissioning is a simulation method, which often takes place after the design is completed. The mechanics are considered as "given" and "unchangeable". The controller and the control are adapted to the mechanics.
• The coupled controller-mechanics simulation is mostly used when the mechanics are still in the design phase (changes are still possible). Both the controller and the mechanics are variable and are iteratively adapted to each other. Thus, the optimization possibilities are many times greater.
