3D Functional Tolerancing and AnnotationWhy do We Need Geometrical Tolerances and AnnotationsStudent Notes:Designers create parts that are generallyrequired to create an assembly of a particularproduct. Each part will be engineered toperform a function and, most importantly, toassemble with a mating part.Thus every part should EXACTLY FIT in thefinal assembly and answer the requestedfunctions.Parts cannot be manufactured to exact sizesbecause of natural imperfections in the world,including machine tools, part programs,tooling, and also human errors. So a plan isneeded to allow the production process toaccept the imperfections. This gave rise to theconcept of “Tolerancing” or “AllowableDeviation”.Copyright DASSAULT SYSTEMESA tolerance is the amount of deviation from the exact size allowed on a part. Any part withinthe tolerance will still be functional.Designers need to set part tolerances that are large enough to keep manufacturing costsdown and close enough to ensure that all parts will assemble with the mating part.It is easy for the designer to use a close tolerance on features to reduce part dimensionvariables; however the part cost increases dramatically as tolerances are reduced.Copyright DASSAULT SYSTEMES7

3D Functional Tolerancing and AnnotationCreating DatumsStudent Notes:Copyright DASSAULT SYSTEMESIn this skillet you will learn the basic principles behind creating Datum Elements andDatum System.Copyright DASSAULT SYSTEMES37
3D Functional Tolerancing and AnnotationWhat is Datum (1/2)Student Notes:Datums are used to identify the datum element in the tolerance frame, specified incase of geometrical tolerancing and on form tolerancing. The Datum element maybe a face of a part. The face marked with Datum, indicates that the face will be areference face and other faces will be machined with respect to this face. A capitalletter is used to identify the datum element.You can specify Datums by following three methods:Simple Datum elementsSpecified Datum systemsCommon Datum elementsCopyright DASSAULT SYSTEMESDatum System CompositionWhen only one identifier is specified in the tolerance frame, the datum is asingle datum.When the identifiers are specified separately in each frame of the toleranceframe, the datum elements represent a datum system. Reference A is theprimary datum and reference B is the secondary datum. Using this datumsystem, fitting will be performed first on datum A, then on datum B, withrespect to A.When two identifiers separated by a dash are specified in the tolerance frame,the datum is a common datum. The two datum elements are to be consideredsimultaneously.Copyright DASSAULT SYSTEMES38

The Hole willbe machined with Datum A and Datum Bfaces.Specified DatumsystemsHole position with respect to the systemcomposed of the face A and face B correctlypositioned respectively to face A.Copyright DASSAULT SYSTEMESCommon DatumelementsCopyright DASSAULT SYSTEMESMiddle portion of the shaft is concentricwith Datum Faces A and B simultaneously.39

Non-Semantic 3Dannotations can be used in case of company defined symbols and syntaxes that are notcovered by standards.When Non-Semantic Annotations are created:Only graphical attributes are taken into account.There is no control over the attribute values.There is no control of consistency regarding the geometryon which it is applied.Non-Semantic Annotations can be created in the form of:Copyright DASSAULT SYSTEMESTextFlag NoteNote Object Attribute (NOA)You can also create these annotations by using ‘ Tolerancing Advisor’ tool.This will be explained in the following slides.Copyright DASSAULT SYSTEMES63
