### Concentricity Tolerance in GD&T: Geometric Dimension and Control

What is Concentricity Tolerance in GD&T? Concentricity tolerance in GD&T controls the central axis of a cylinder or sphere with respect to the datum plane or an axis. It also controls the median points of cylindrical parts.For example, in transmis ...

### GD&T Straightness Tolerance : Geometric Dimension and Control

GD&T Straightness is a type of foam control tolerance that is used to control the line on a surface / feature or an axis. In other words straightness controls a condition where all elements of a surface or an axis lies in a straight line. Datum planes ...

### GD&T Parallelism Tolerance : Geometric Dimension and Control

Parallelism tolerance in gd&t is a type of orientation control tolerance that controls the parallelism of two lines, surfaces or axis. It does not control the angle of the referenced feature. But it creates a tolerance zone of two parallel planes wher ...

### GD&T Basics: Introduction to Geometric Dimension and Tolerance

What is GD&T tolerances? Geometric dimension and tolerance ( GD&T ) is a type of tolerance that are used along with linear tolerance to define nominal and allowable variations in the part geometry or an assembly. ASME Y14.5-2009 standard has defin ...
