Taking the distortion of component parts along a manufacturing chain into consideration during planning

Abstract

Distortion of a component part can already be minimized if it is
considered in the planning of the manufacturing process. Thus,
costs of the removal of distortion, e. g. by grinding, can be reduced.
Beginning with steel production the state of a workpiece changes
every process step continuously. Thereby, a distortion potential
arises that will be visible at the component part after hardening
as distortion. To consider distortion in planning the state has to
be determined at every time of manufacturing. So far, no tools exist
to describe the workpiece state along an entire process chain. In this
article an alternative will be presented which is able to describe
changes of states along an entire manufacturing chain. Finally,
with this description an estimation of the expected distortion can
be carried out.
Key words: Distortion, manufacturing chain, planning, workpiece
