SPP 1138:  Modelling of Scaling Effects on Manufacturing Processes

Subject Area Mechanical and Industrial Engineering
Term from 2002 to 2008
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5471677
 
Scaling effects are defined by the occurrence of a not directly predictable change of the process parameters, if a process was scaled in correct similarity relations. The aim of this priority program is to clarify the influence of size appearing at the scaling on manufacturing processes, where plastic deformation of metal material takes a central part, and thereby influences the result of the process. The approaches to be developed should be able to describe the observed phenomena. Thereby an understanding of the limit of processes should be developed, which are due to geometrical, plastic or dynamical instability. It is desirable that the knowledge joined by the analysis of scaling effects on manufacturing processes, lead to novel processes. The main focus is set on the following points: 1. Modeling of the material-behaviour in the process. 2. Developing similarity-material characteristics. 3. Validation of scaling effects.
