How is angularity tolerance measured?
Beside this, what is tolerance for basic dimension?
Basic dimension: A basic dimension is a numerical value used to describe the theoretically exact size, profile, orientation, or location of a feature or datum target. The tolerance associated with a basic dimension usually appears in a feature control frame or a note. The Basic Dimension has a box around the dimension.
Subsequently, question is, how do you define position tolerance? ) is a geometric dimensioning and tolerancing (GD&T) location control used on engineering drawings to specify desired location, as well as allowed deviation to the position of a feature on a part.
Also asked, how do you measure perpendicularity?
Perpendicularity is measured using a height gauge, similar to flatness, however, the gauge (or part) is locked to a 90° datum to measure how perpendicular the surface is. The entire surface has to be measured if it is a flat feature.
How is parallelism measured in GD&T?
Gauging / Measurement: Parallelism is quite simple to measure. Like flatness, a gauge is run across the reference surface or feature. However, unlike flatness, the part is constrained against a granite block or flat plane that acts as the datum surface where it is measured.
