Unformatted text preview: in Fig. 1(b) for the rectangular face conforms with diagrams and spaces presented by others for representing size-tolerances. [Whitney, et al., 1994] obtained the shape using an intuitive argument. [Roy and Li, 1999] used inequalities to establish a variation zone of acceptable ranges of the coordinates for any plane in the tolerance-zone. [Giordano, et al., 1999, 2001] get a dipyramidal deviation space using the same method. The T-Map for an axis, such as for one of the holes in the plate of Fig. 2(a), is a 4-D solid of points. Although this solid cannot be viewed directly, it can be visualized with 3-D hypersections in which one of the four coordinates, L', M', P, and Q, is held fixed; one representative hypersection of it is shown in Fig. 2(b). (Note: In the plan (top) view of Fig. 2(a), L' and M' represent tilts of the axis to the left-or-right and fore-or-aft, respectively, and P and Q represent translations of the axis in the same directions, respectively.) The method of [Giordano, et...
