Learn how to control position of an interrupted hole by treating it as a single feature or as separate features with simultaneous requirements.
In this Question Line video, Jason answers questions regarding True Position and how to calculate diametric deviations. He discusses the difference between "True Position" and "Position" and walks through the process of determining whether the part passes inspection.
In this question line video, Jason explains how to control radial position with a composite tolerance by walking through an example of a pattern of holes on a cylinder.
Jason walks through an example showing how to inspect a hole with position at an angle, rather than parallel or perpendicular, to the primary datum.Â
Though many people refer to the GD&T Position symbol as "True Position," they are not the same thing. Read on to learn the difference between Position and True Position and how they work together to define the position of a feature.
In this question line video – Tom discusses how to understand a curved profile surface as a datum for 4 holes that are required to remain normal to the irregular surface. How do we do...
Controls exactly where a feature must be located. Uses a circular tolerance zone and works with MMC — the most used symbol in GD&T.
