Tolerancing a solid model with a kinematic formulation
Louis Rivest, Clément Fortin, Claude Morel · 1993
TIE thmcdimms ksnal analysis of tolcraneu is one of the critical functional requirements of solid modeling systuns which is most Iaeking at the pracnt time.The 3D toloranec analysis, whcncarricd out byhand, ia moat dif&mltandsomdma impossible to realim whm applied in 3D fir complicated goomstries.A kincmatio formulation to the full 3D dimcasitmal and goomstrieal toloranec modding particularly qqdicd to the manufacturing ~il-~-.~representsalltokranecd withakinemadc ohainwithin atcohnotopological model, Whioh is Oompatiik with existing Stand@s such as ANSI Y14.5M.The sanantiu of tolaanea is mspcdcd as tolerances are q utomadeally interpreted to @d tolcranoc Zme4 while their meaning and syntax arc validated.The eonee@ has been implementedon the PADL-2 solid modeler but could be easily appliedto other exact solid modelers.Toleranec induced topologicallinksarc addedto the did modelerrepresentation and allow the user to visualizethe cxaet dimeaaionand shapeof ths resulting tolcranec zone.The eonccpt ean be applied to manipulatemultiple tolcraneu in order to solve 3D tolcranee transfer problems.
