"Webb21 juni 2024 · The profile of a line tolerance is a 2D GD&T callout that can define and control a linear/curved feature or a surface cross-section within specified limits. We can use it to control the form, location, orientation and size of a feature. This callout can only be used on surfaces and cannot be used to locate a central axis or plane.

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.

WebbGD&T symbol. There is no dedicated symbol specifically for sphericity in either the ISO or ASME GD&T standards. Typically, sphericity will either be defined using a roundness callout, or a profile of a line or surface. A profile of a line or surface can control form, size and optionally position with datums. The profile of a surface is an extremely powerful and versatile GD&T callout. It can be used on nearly all kinds of complex outer shapes where other tolerances are not easily applicable. Some examples of surface profile use: 1. Aerospace: airplane wing, air intake for engine, turbine blades 2. Automotive sector: BiW, A … Visa mer The surface profile tolerance zone consists of two parallel planes, bilaterally disposed on each side of the ideal curved surface (aka the true … Visa mer As mentioned above, the profile of a surface can effectively replace almost all of the GD&T Callouts whether they are curved or flat.
