WebbBy default, on a non-planar feature, profile will always control size and form of the surface. When this modifier is added, the profile controls the form of the feature without size. The offset between the profile boundaries remain fixed but the size of … WebbThe profile tolerance zone will float within the size tolerance zone, and the profile tolerance zone will be exactly 99.5 degrees to datum [A] and exactly perpendicular to datum [B]. Finally we control the location, orientation, and form of the bottom of the slot with a profile of a surface that has a 0.5 wide tolerance zone.

WebbProfile of a surface is a GD&T symbol used with datum if you want to control every aspect of a feature’s geometry like size, shape, orientation, and even location . Practically, profile of a surface can be checked with a CMM that can measure the actual, as-produced surface compared to the theoretically exact surface (True profile).

WebbThe surface could be an external or an internal feature – roundness can apply to holes as well as shafts. As long as the profile is rotationally symmetric in some location, roundness may apply. See some examples in this image, showing a blue plane where roundness may apply: What standards apply to GD&T roundness and circularity? WebbGD&T isn’t applied at a high level on as-cast hole positions and diameters nor on as-cast surface profiles. Yet, that is where GD&T has its greatest potential in enabling more as-cast, net shape, lower cost features. The most likely reason that Position and Profile Tolerances are so underutilized in casting design is the apparent complexity.
