Definitions:

Diametral Pitch

A value describing the ratio of the number of teeth of a gear to the diameter of the pitch circle, used in the design and specification of gears.

Circumference

The perimeter or boundary line of a circle, often measured to understand the size or to describe the distance around it.

Bevel Gear

A type of gear where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped, often used in differential drives.

Addendum

The radial distance from the pitch circle of a gear to the top of the teeth.
