The scope of this work was the research of fundamentals for the computer assisted multi-objective design of complex actuator systems for laser micro adjustment. Several criteria for the design of such actuator systems were identified. These criteria are in part conflicting. A focus of this work lay on the automatic evaluation of actuator design variants in respect of the single criteria. To this end several new data formats and algorithms were developed. The assessment of the adjustment capabilities within the course of a computer assisted, iteratively optimizing design process was made possible through the approach of fast simulation via virtual thermal forces introduced in this work. The algorithms were implemented into a design system using multi-objective genetic algorithms. The fast simulation of laser micro adjustment via virtual thermal forces developed in this work can be transferred to other problems. It is applicable where laser forming of small sheet metal constructs has to be evaluated in a timely fashion.
