Unformatted text preview: J-K & Pb. 3. TOLERANCE ALLOCATION AND ANALYSIS The objective of this analysis is to control the orientation and lateral position of the saw blade. The sequence of engaging parts from the frame to the saw blade are : axis E-F (orientation of the arm) and face M (position of the arm) ; surfaces D, G1, and H1; seating of the ball bearing in the pocket E2; support of the spindle at the two bearings; and clamping of the blade, collar, and inner race of the ball bearing against face Q on the spindle. The target is the face of diameter db on the collar (Fig. 4(d)). Starting at the blade, the T-Map in Fig. 5(a) is for the stackup from Q (bearing inner race and the collar); its height is the sum of the last 3 terms in eqn (2), and its radius is the last 2 terms in eqn (3). It was formed using the methods in [Davidson, et al., 2002]. Fig. 5(a) reflects a truncation of Fig. 1(b) by a cylinder. This shape comes from the orientational tolerances t"Pa and t"Pb, respectively, that could be applied...
