The 1D clearance can be determined from multidimensional variations of the medial-plane for a slot or a tab, and from variations of both medial-planes in a tab-slot assembly. The model is compatible with the ASME\/ANSI\/ISO Standards for geometric tolerances. Central to the new model is a Tolerance-Map (Patent No. 6963824) (T-Map), a hypothetical volume of points that models the range of 3D variations in location and orientation for a segment of a plane (the medial-plane), which can arise from tolerances on size, position, orientation, and form. Here it is extended to model the increases in yield that occur when the optional maximum material condition (MMC) is specified and when tolerances are assigned statistically rather than on a worst-case basis. The frequency distribution of 1D clearance is decomposed into manufacturing bias, i.e., toward certain regions of a Tolerance-Map, and into a geometric bias that can be computed from the geometry of multidimensional T-Maps. Although the probabilistic representation in this paper is built from geometric bias, and it is presumed that manufacturing bias is uniform, the method is robust enough to include manufacturing bias in the future. Geometric bias alone shows a greater likelihood of small clearances than large clearances between an assembled tab and slot. A comparison is made between the effects of specifying the optional MMC and not specifying it with the tolerance that determines the allowable variations in position of a tab, a slot, or of both in a tab-slot assembly. Statistical tolerance assignment for the tab-slot assembly is computed based on initial worst-case tolerances and for (a) constant size of tab and slot at maximum material condition, and (b) constant virtual-condition size.<\/jats:p>","DOI":"10.1115\/1.3249576","type":"journal-article","created":{"date-parts":[[2010,3,10]],"date-time":"2010-03-10T18:29:22Z","timestamp":1268245762000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":14,"title":["Statistical Tolerance Allocation for Tab-Slot Assemblies Utilizing Tolerance-Maps"],"prefix":"10.1115","volume":"10","author":[{"given":"Gaurav","family":"Ameta","sequence":"first","affiliation":[{"name":"School of Mechanical and Materials Engineering, Washington State University, Pullman, WA 99163"}]},{"given":"Joseph K.","family":"Davidson","sequence":"additional","affiliation":[{"name":"School of Mechanical, Aerospace, Chemical and Materials Engineering, Arizona State University, Tempe, AZ 85827-6106"}]},{"given":"Jami J.","family":"Shah","sequence":"additional","affiliation":[{"name":"School of Mechanical, Aerospace, Chemical and Materials Engineering, Arizona State University, Tempe, AZ 85827-6106"}]}],"member":"33","published-online":{"date-parts":[[2010,2,16]]},"reference":[{"volume-title":"Dimensioning and Tolerancing","author":"American National Standard ASME Y14.5M","key":"2019100513273996000_c1"},{"volume-title":"Geometric Tolerancing\u2014Tolerancing of Form, Orientation, Location, and Run-Out\u2014Generalities, Definitions, Symbols, and Indications on Drawings","author":"International Organization for Standardization ISO 1101","key":"2019100513273996000_c2"},{"key":"2019100513273996000_c3","doi-asserted-by":"publisher","first-page":"609","DOI":"10.1115\/1.1497362","article-title":"A New Mathematical Model for Geometric Tolerances as Applied to Round Faces","volume":"124","author":"Davidson","journal-title":"ASME J.
