Engineering Drawings and Tolerances

Flashcards covering important vocabulary related to engineering drawings, section views, and tolerances.

Section View

A drawing representation that shows a view of an object as if it has been cut through at a particular plane.

Crosshatch

Lines used in section views to denote cut surfaces, often varying based on material.

Cutting Plane Line

A line that indicates where a section view slice occurs in a drawing.

Tolerance

The total permissible variation in size allowed in manufacturing a part.

Basic Size

The theoretical or design size from which limits of size are defined.

Limits of Size

The maximum and minimum allowable sizes for a part.

Limit Dimensioning

A method of specifying size by providing both maximum and minimum values.

Plus Minus Tolerance

A tolerance specification that allows a dimension to vary above and below a basic size.

Maximum Allowable Size

The highest size a part can be while still falling within specified tolerances.

Minimum Allowable Size

The smallest size a part can be while still falling within specified tolerances.
