The T-Map for orientation and position together is formed most reliably by truncating the T-Map for position alone. Keywords: form tolerance, position tolerance, straightness, axis, Tolerance-Map. 1. INTRODUCTION AND LITERATURE REVIEW When a part is to be manufactured, there are allowable geometric variations for its features. As explained in the ASME Y14.5M Standard [ASME,1994] and the ISO 1101 Standard [ISO,1983], the allowable geometric variations are specified using three-dimensional tolerance-zones in which the feature is permitted several degrees of freedom for displacement. The tolerance-zone is located with a basic dimension. The shape of the tolerance zone is defined by the type and value of the tolerance and the feature to which it 1 Patent No. 6963824. 45 J.K.
