11.10.2 Dynamic Profile Tolerance Controlling Form and Orientation When the dynamic tolerance modifier is applied to a lower segment of a composite tolerance and includes datum feature references, the tolerance zone controls the form and orientation but not the size of the feature. See Figure 11-36. The 2 profile tolerance zone is constrained in translation and rotation relative to the datum reference frame established by datum features A, B, and C. The 0.4 dynamic profile tolerance zone in the lower segment of the composite tolerance is constrained in rotation but not translation relative to the datum reference frame. This tolerance zone may expand or contract while maintaining the form and orientation of the feature within the 0.4 tolerance zone, allowing the size of the feature to uniformly progress. The actual feature shall simultaneously be within both tolerance zones. 11.10.3 Dynamic Profile Tolerance Applied to the Lower Segment of Multiple SingleSegment Feature Control Frames When the dynamic profile tolerance modifier is applied in a segment of multiple single-segment feature control frames and includes datum feature references, the tolerance zone is constrained in translation and rotation, but not size, as applicable. The tolerance zone controls the form and orientation of the feature. See Figure 11-37. The 2 profile tolerance zone is constrained in translation and rotation relative to the datum reference frame established by datum features A, B, and C. The 0.4 dynamic profile tolerance zone in the lower segment is constrained in translation and rotation relative to the datum reference frame. This tolerance zone may expand or contract while controlling the form, orientation, and location of the feature within the 0.4 tolerance zone, allowing the size of the feature to uniformly progress. The actual feature shall simultaneously be within both tolerance zones. NOTE: Multiple features are considered to be a single feature unless “INDIVIDUALLY” follows a separate single-segment profile feature control frame. 11.10.4 Dynamic Profile Tolerance Applied to a Surface of Revolution The dynamic profile tolerance may be applied to surfaces of revolution to maintain the shape of the considered feature while allowing its size to vary. See Figure 11- 38. The entire surface between A and B shall be within the profile tolerance of 0.25, which is equally disposed about the true profile. The 0.15 dynamic profile tolerance zone in the lower segment is constrained in translation and rotation relative to the datum reference frame. This tolerance zone may expand or contract while controlling the form, orientation, and location of the feature within the 0.15 tolerance zone, allowing the size of the feature to uniformly progress. The actual feature shall simultaneously be within both tolerance zones. ASME Y14.5-2018 245
