Study on Driving Force by Coupling Constraints in NC Equipments Grid

摘要

The burgeoning grid technology provides a practical possibility to share Numerical Control(NC) equipment under a Web environment via many-to-many mode which is faced with the difficulty of a driving force for grid workflow.This paper proposes the novel methodology of coupling constraints to overcome this difficulty.First,the complex constraints and the structure attributes of NC tasks are detailed in the NC equipment grid that illustrates the possibility of forming a grid workflow force by coupling constraints.Second,the principle of driving force by coupling constraints in an NC equipment grid and the relative algorithm are proposed.Finally,the case study of comparative experiment is detailed to demonstrate the efficiency of this novel tactic.
