Flatness Tolerance: GD&T Basics

Flatness is a type of foam control. It controls the variations in flat surface, regardless of any datum feature. It ensures required surface is flat enough to perform required function. Flatness value is always less than the dimensional tolerance associat ...

Parallelism Tolerance : GD&T Basics

Parallelism is a type of orientation control tolerance. It controls parallelism between two lines, surfaces or axis. Parallelism does not controls the angle of the referenced feature. it creates a tolerance zone where all points of the feature must lie. Y ...

Limits Fits and Tolerance

Engineering Tolerances are required evil. You can not live without then while working with manufactured parts. But for robust design we need to find a way in between

General Tolerance :ISO-2768

What is Engineering Tolerances ?Engineering tolerance is the total amount a specific dimension is permitted to vary. They are required because It is not possible to manufacture 100% accurate parts. Manufacturer always try to approach for true value as clo ...
