Abstract:
The concept of variational geometric constraints network is
presented. Based on ISO’s feature, three kinds of variational
geometric constraints are defined. The concepts of mate tree
(MT) and loop circuit (LC) are presented. The generation method
of well-constrained variational geometric constraints network (VGCN)
is studied. The network can be applied in generation of
well-constrained tolerance types and tolerance chains. A simple
example is analyzed to show the scheme to be effective.
