Abstract :
The paper analyzes the mating natures of a 2D polygonal assembly and discusses uncertainty in assemblies due to the geometric (size and shape) variations of the assembled parts. To study variant assembly configurations, translational and rotational motion constraints are generated by analyzing geometric contact relations between variant parts. Based on these motion constraints, the uncertainty build-ups in an assembly of toleranced parts are investigated
