Slot Profile Tolerance
The tolerance of the slot in Figure 14.50 is.004' and the tolerance of the mating part is.002'.
The position tolerance controls the location and orientation of the slot to the datum reference frame. In this case, there is an inner boundary that the slot may not violate. The slot can move left, right, up or down, and even tip, as long as it does not come inside this boundary, which is probably the space needed by the mating part. Description: Profile of a surface describes a 3-Dimensional tolerance zone around a surface, usually which is an advanced curve or shape. If it is called out on a curved surface, like a fillet on a welded part, the entire surface where the radius is has to fall within the tolerance zone. Processes and common tolerances associated with them as a function of typical part size. The important point to take away fr om this figure is the general trend showing typical achievable part tolerances grow as a function of parts size. In other words, the ability to achieve a certain tolerance is a function of part size. A slot, by nature, would normally need different tolerances differing horizontal to vertical. That's why in the standard you normally see composite feature control frames to specify the tolerance around the true position of a slot. The orignial question by Proedj seemed to indicate that he wanted a diametrical tolerance zone.
