One math tool, the kinematic transformation, is used for the first time to construct Tolerance-Map\u00ae (T-Map)\u00ae models of geometric and size tolerances that are applied to planar faces and to the axes of round shapes, such as pins or holes. For any polygonal planar shape, a generic T-Map primitive is constructed at each vertex of its convex hull, and each is sheared uniquely with the kinematic transformation. All are then intersected to form the T-Map of the given shape in a single frame of reference. For an axis, the generic T-Map primitive represents each circular limit to its tolerance-zone. Both are transformed to a central frame of reference and are intersected to form the T-Map. The paper also contains the construction for the first five-dimensional (5D) T-Map for controlling the minimum wall thickness between two concentric cylinders with a least-material-condition (LMC) tolerance specification on position. It is formed by adding the dimension of size to the T-Map for an axis. The T-Maps described are consistent with geometric dimensioning and tolerancing standards and industry practice. Finally, transformations are presented to translate between small displacement torsor (SDT) coordinates and the classical coordinates for lines and planes used in T-Maps.<\/jats:p>","DOI":"10.1115\/1.4038821","type":"journal-article","created":{"date-parts":[[2017,12,23]],"date-time":"2017-12-23T19:01:07Z","timestamp":1514055667000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":3,"title":["Mathematical Tools for Automating Digital Fixture Setups: Constructing T-Maps and Relating Metrological Data to Coordinates for T-Maps and Deviation Spaces"],"prefix":"10.1115","volume":"18","author":[{"given":"N.
