What Is Profile Tolerance? In GD&T, profile tolerance defines a uniform boundary around a surface within which the elements of the surface must lie. Profile is a complex tolerance that simultaneously controls a feature’s form, size, orientation, and sometimes location. … The top figure shows the profile tolerance applied to a curved surface. How is
Does Profile Tolerance Control Position? When used with datums, profile can mimic all the orientation symbols (perpendicularity, parallelism, angularity) and even control the location and size of a feature or surface. … All of these symbols have a tolerance zone existing of parallel surfaces surrounding the measured profile. Does position tolerance control size? Since the
What Is S In GD? The circle S is a now discontinued practice that just means that the tolerance or the datum is to be taken at regardless of feature size. This symbol was phased out in the 1994 standard because it was deemed redundant with not putting anything there at all. What does an
