Unformatted text preview: of the Tolerance-Map, those shown in Fig. 2. Since the perpendicularity tolerance limits only the orientational variations of the axis, the T-Map will be truncated only in the directions of the L' and M' axes and will remain unchanged in directions parallel to the axes P and Q that correspond to translational variations; the truncation is accomplished with two parallel planes separated by the dimension t". Two truncated hypersections can represent all four that would result from Fig. 2 because Figs 2(a) and (c) contain only one orientation axis (L' or M') while the sections represented by Figs 2(b) and (d) contain both orientation axes (L' and M') together. When Fig 2(a) is truncated, the result is the hypersection shown in Fig 4(a); except for a minor re-labeling, it applies also when Fig 2(c) is truncated. For the hypersections in Figs 2(b) and (d), the T-Map is truncated by a cylinder of diameter t"; the result is shown in Fig 4(b). 5. TOLERANCE MAP FOR AN AXIS TO BE PARALLEL TO A FACE Suppose now that, instead of the perpendicularity tolerance of t" being applied to the axis of the larg...
