Amatrol’s Geometric Dimensioning and Tolerancing (MXBP204) training course introduces the learner to the underlying concepts and practices of GD&T. The course focuses on understanding dimensions and tolerances on engineering drawings per the ASME Y14.5M-1994 standard. The learner studies datums, geometric rules and types, GD&T characteristics, tolerance types, and tolerance zones.
What is Conventional Tolerancing? How are They Specified on a Drawing?
A tolerance is the total amount by which a specified dimension is allowed to vary. One way to specify a tolerance is to show the plus and minus tolerance value next to the nominal dimension. This is called conventional tolerancing.
There are two ways conventional tolerances are specific on a drawing:
- Bilateral Tolerance: A bilateral tolerance means that the actual dimension can be either larger or smaller than the dimension shown on the drawing. If the amount of variation in either direction is the same, the bilateral tolerance is indicated. In some cases, the tolerance of a dimension must be made smaller in one direction than another because of the design needs of the part, or the assembly into which the part is being assembled.
- Unilateral Tolerance: In certain cases, the dimension of the part can only be allowed to vary in one direction. The amount that the dimension can vary in this one direction is called a unilateral tolerance.
