Flatness Vs. Surface Profile - FullyInstrumented
Flatness and surface profile lie in two different fundamentals of GD&T (out of a total of four) namely, flatness is categorized as “form”, while the surface profile is categorized as a feature of “profile”.
Flatness Vs. Profile Controls - TES-technologies
Flatness is a tolerance used for form alone, and is not able to control position and orientation of surfaces (not even within a group). In such a case, each surface has an independent tolerance zone; Flatness controls the form of each surface separately, and does not control the position or the relative orientation between the two surfaces.

2022年5月10日 · 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. There are times when both profile controls may be applied together.

Flatness vs. Profile of a Surface. Flatness and profile of a surface are often confused due to their surface-related definitions in GD&T. However, while flatness specifies how close a surface is to being perfectly flat, profile of a surface defines a more complex form.
Profile - Dimensional Consulting
Profile is always applied to a surface, so profile can control the form of a surface. Profile cannot control the form of a derived median line or a derived median plane of a feature of size. We have seen flatness called out on a surface as on the left in the figure below.

2021年3月30日 · Flatness is the 3D equivalent of the surface straightness control. While straightness has parallel lines representing its tolerance zone, the flatness tolerance zone is formed by two parallel planes.
Profile of a Line vs. Profile of a Surface - Metal Cutting Corporation
2020年4月29日 · Surface profile is also commonly called out for: Cast parts with curved surfaces where the amount of variation needs to be controlled; Complex designs where two parallel surfaces of the same shape must fit together; Profile Line vs. Surface Profile in Precision Parts
Practical GD&T: Flatness Measurement - Basic Concepts - Redlux
Flatness vs profile of a surface. Another alternative to using a flatness control is to use the generic profile of a surface constraint. Applied to a planar surface, this will achieve many of the constraints on surface form which a flatness callout can.
Practical GD&T: Profile of a Surface – Basic Concepts
The ‘profile of a surface’ (sometimes simply ‘surface profile’) control is used in GD&T (geometric dimensioning & tolerancing) to control the form of any 2D surface in 3D space. It is one of the most powerful GD&T controls and can be used with complex freeform geometries.

2024年5月3日 · Surface Profile tolerance specifies a uniform boundary that the surface must lie within. It controls the shape, rather than the size or location, of a surface. Surface Profile is often used when the surface needs to fit with another surface or …
