Computer Aided Tolerancing for the methodical design process
#ISO 5459 FREE PDF VERIFICATION#
Technische Universität Chemnitz work together to derive requirements for datum systems based on the functional (nominal) and the verification (real) aspects understanding the importance of the datum system for the quality of the workpiece.Ģ.1. Therefore, design and measurement engineers at

The current state of scientific knowledge on this subject still shows gaps in how to derive a datum system in a function-oriented design process as well as what are standard definitions for extraction and association for the verification process. The recent attempt in GPS to change from dimensional to geometrical tolerancing leads to a stronger focus on datum systems, being also a complex part within the GPS system. GPS provides the rules for an unambiguous description and verification.

It will also show current research results to overcome the gaps in ISO 5459 about extraction and association requirements for the verification process. A new approach to develop a functional datum system in the early stages of the methodical design process that is derived from the functional interaction of the indeterminate workpiece geometry within the outlined assembly group will be explained. Two aspects on the requirements for these and their effects on each other will therefore be discussed in this paper.
