The profile of a surface symbol is a half-circle with the curved edge facing up and the flat edge on the bottom. On the feature control frame, the box to the right of the Profile of a Surface symbol contains the tolerance for the surface.
What does line profile mean?
Description: Profile of a line describes a tolerance zone around any line in any feature, usually of a curved shape. Profile of a line is a 2-Dimensional tolerance range that can be applied to any linear tolerance.
What is difference between profile of line and profile of surface?
In other words, while profile of a line looks only at a specific cross section, profile of a surface looks at how measurements vary from one cross section to the next.
What is profile of a line in GD&T?
The profile of the line requirement indicates whether the curvature of a designed part is made to its design. The value indicates any distortion in the profile line (line element that appears on the cross-section of a surface).
What is surface profile in GD&T?
The profile of a surface specification defines a 3-dimensional tolerance zone equidistant from the theoretically exact shape or curve (i.e. the “True Profile”) to control all the points along the surface to be within a tolerance range.
Does surface profile need a datum?
Profile can control, form, location, orientation, and size or any subset of these. Profile can be used with or without datum references and with or without basic dimensions.
Can a surface profile be a datum?
This surface acts as the primary datum in terms of how the part will seat/mate functionally in the assembly. My intent is to identify this surface as Datum A with a profile tolerance which is essentially creating a virtual condition boundary for the form of the feature.
What is profile in drawing?
Profile drawing means a scaled graph or plot that represents the side view of an object. Objects may include a surface water body or a portion of it, a man-made channel, an above-ground structure, a below-ground structure, a geographical feature, or the ground surface itself. Sample 1. Sample 2.
How do I find my profile line?
To get information registered with LINE Profile+ via LIFF App or LINE MINI App, set the scopes of information you want to obtain on the LINE Developers Console, then get ID token payload, and you will be able to obtain the LINE Profile+ information of currently logged-in users.
Is profile tolerance bilateral?
Bilateral profile tolerance means variation from the true profile is permitted in equally in both directions. Unequally disposed profile tolerance means that more variation from the true profile is permitted in one direction than the other.
What is profile measurement?
Overview. Profile measurement systems measure and record the profile of a target by tracing the surface of the target using a stylus. Some instruments can even be used as surface roughness meters.
