Possibilities to describe distortion along Process chains

Abstract

During the decade of the Collaborative Research Center CRC 570 Distortion Engineering many methods were developed and extended. Within this paper these methods are evaluated in respect of practical application in process planning. The methods can be arranged by two different targets. On the one hand by mainly consider distortion up to predict distortion to support planning. The similarity of all methods is given due to the fact that distortion has to be seen as a system attribute. After the introduction of the methods and their basic functionality they were evaluated against process planning in particular the planning types `repeat planning´ up to `new planning´. Generally it can be shown that the transferability on other geometries, processes and materials is strongly limited. Furthermore the methods which only consider distortion seem better to fulfill the tasks of the planning types as methods which determine distortion. The best method was the method which compares different process chains. Nevertheless, this more theoretical evaluation has to be verified by industrial process planning.
