GD&T stands for Geometric Dimension and Control is a type of tolerance used to define the geometry of a component. It is extensively used by design engineers to define design intent for a part. In this article, we will discuss top GD&T interview q ...
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 w.r.t. the datum plane or an axis. In other words, it ensures the median points of cylindrical parts are within limits.For e ...
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 ...
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 whe ...
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 used along with linear tolerance to define nominal and allowable variations in the part geometry or an assembly. ASME Y14.5-2009 standard has defined differ ...
