Abstract
Geometrical tolerancing can best be described as a language of symbols placed on technical drawings to adequately define the allowable variation of part geometry. The chapter provides categories of engineering drawing practice—such as general principles, dimensioning, and size tolerancing—and explains when to use a geometrical tolerance. A geometrical tolerance is the maximum allowable variation of form or position of a feature. The size tolerance of a dimension has a certain amount of control over form and attitude, but if a better degree of control is required, geometrical tolerances should be used. The chapter also discusses orthographic representation of various two-dimensional technical drawings. The two orthogonal projection methods used internationally are first angle projection and third angle projection.
