Max material condition and bonus tolerance

WebMaximum Material Boundary (MMB) is a boundary that the datum feature of size will not violate. The MMB is calculated by combining the MMC size with any applicable geometric tolerance on the datum feature of size. The MMB is always outside the material. The figure below shows one example of a Maximum Material Boundary WebMaximum Material Condition m, or Least Material Condition l , must be specified on drawing where it is required . The rule can be applied to the design drawing shown in Figure 4. Due to the nature of the control, RFS can be applicable at most of geometric characteristics exce pt at three Form Tolerances: Flatness, Circularity, and Cylindricity.
