Profile of a Surface | GD&T Basics
2014年12月18日 · Profile is the catch-all symbol for surface control in Geometric Dimensioning and Tolerancing. If it cannot be controlled with another symbol, profile is your best bet. When used with datums it can control every aspect of a feature’s geometry which includes size, location, orientation, and form.

Profile of a Surface (GD&T) Explained - Fractory
2022年5月10日 · The profile of a surface tolerance is the 3D equivalent of the line profile tolerance. While the profile of a line controls a specific cross-section on the part, the profile of a surface controls every cross-section across the entire length of the surface.
Profile of a Surface – Unilateral vs. Bilateral | GD&T Basics
2021年4月12日 · On the feature control frame, the box to the right of the Profile of a Surface symbol contains the tolerance for the surface. The tolerance zone consists of two parallel profiles that follow the True Profile. The tolerance zone can be bilateral or unilateral.

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.
Easy Guide to GD&T: Profile of a Surface[ Symbol, Tolerance, Measurement ]
2024年2月16日 · In GD&T the Profile of a Surface symbol is used to establish a 3 dimensional tolerane zone around the surface, which is often a complex curve or shape. This control requires that every point on the surface must lie within a tolerance range that mimics the surface profile.
