Deck 12: Cylindricity Tolerance

Question 1

Explain the tolerance zone for a cylindricity tolerance.

Answer 1

The tolerance zone for a cylindricity tolerance is the space between two coaxial cylinders. The distance between the cylinders is equal to the cylindricity tolerance value. The tolerance zone applies to the entire cylindrical surface. All points of the cylindrical surface must be within the tolerance zone. The diameter of the tolerance zone is established from the toleranced cylinder.

Question 2

Circularity is a perfect condition.

Answer 2

True

Question 3

Where a cylindricity tolerance is applied to a surface that is associated with a size dimension, and Rule #1 applies to the size dimension, the cylindricity tolerance value must be ____________________ the difference between the size tolerance limits.

Answer 3

less than

Question 4

A cylindricity tolerance is always applied to ____________________ elements of a surface of revolution.

Question 5

Where a cylindricity tolerance is applied to a cylindrical surface, the tolerance zone applies along the entire length of the cylinder.

Question 6

Where a cylindricity tolerance is applied to a cylindrical surface, the cylindricity tolerance does not override ____________________.

Question 7

Rule #1 is a direct form control.

Question 8

Surface texture deviations are included in a cylindricity tolerance zone.

Question 9

When the feature of size is at ____________________, the surface must be perfectly cylindrical.

Question 10

A cylindricity tolerance is a geometric tolerance that defines the ____________________ permitted on a cylindrical surface.

Question 11

Explain how the circularity deviation is verified when a cylindricity tolerance is applied to a cylinder.

Question 12

What are three real-world applications of a cylindricity tolerance on a drawing?

Question 13

A cylindricity gauge is an instrument used to measure cylindricity deviation.

Question 14

Define cylindricity.

Question 15

Explain how Rule #1 affects cylindricity of a surface.
