| 摘 要： | The concept of variantional geometric constraints network is presented. Based on ISO's feature, three kinds ofvariational geometric constraints are defined. The concepts of mate tree (MT) and loop circuit (LC) are presented. Thegeneration method of well-constrained variational geometric constraints network (VGCN) is studied. The network can beapplied in generation of well-constrained tolerance types and tolerance chains. A simple example is analyzed to show thescheme to be effective.
