An axis of perfect form (subset T-Map of size zero) is shown in the Fig 3(a); its range of position is the entire tolerance-zone for position, and its T-Map is represented by the hypersection of dimension t. In Fig 3(b), the axis has an imperfect form that has an intermediate measure less than t'. Fig 3(c) shows the measure of form equal to t', the limit for the axis of the smaller hole in Fig. 1(a). (a) (b) (c) (d) Figure 3. The tradeoff between internal subsets for straightness and range of positions, which lie within the T-Map for the axis of the smaller hole in Fig 1(a). Tolerance-Maps for Straightness and Orientation 51 When no tolerance on straightness is specified, Fig 3(d) provides the upper limit on form variation, as suggested by Rule #1 in the Standards: all the lines in the tolerance-zone on position are devoted to form, the floating zone completely fills the tolerance-zone on position, and its T-Map is the same as that for position, i.e. it has dimension t. 4. TOLERANCE MAP FOR PERPENDICULARITY OF...
