Deck 20: Position Tolerance - Introduction

Question 1

Where a position tolerance applies at RFS, it is interpreted as a boundary tolerance zone.

Answer 1

False

Question 2

Where a position tolerance is applied at RFS, what three conditions apply?

Answer 2

Where a position tolerance is applied at RFS:
1. The axis interpretation is used.
2. The axis of the unrelated actual mating envelope must be located within the tolerance zone.
3. The orientation is controlled relative to the primary datum referenced.

Question 3

____________________ position is the theoretically exact location of a feature of size as established by basic dimensions.

Answer 3

True

Question 4

List the six important advantages of using position tolerance in comparison to coordinate tolerance.

Question 5

Where a position tolerance is specified at RFS and applied to a(n) ____________________, the center plane interpretation applies.

Question 6

A position tolerance is always applied to a feature of size or pattern of features of size.

Question 7

What are the two common tolerance zones shapes for a position tolerance?

Question 8

____________________ is the default condition for the tolerance value and size datums referenced at RFS.

Question 9

Basic dimensions are required to locate and orient the feature(s) of size relative to the datum features referenced in the feature control frame.

Question 10

What are the four requirements to correctly specify a position tolerance?

Question 11

Position tolerances are commonly used to control four types of part relationships. Name them.

Question 12

Where a position tolerance is specified at ____________________, the tolerance zone is a virtual condition boundary located at the true position of a feature of size which the surface(s) of the feature of size must not violate.

Question 13

In an RFS application, the position tolerance zone is a constant value, regardless of the size of the toleranced feature of size.

Question 14

A position tolerance applied to a feature of size affects its size.

Question 15

Where a position tolerance applies at ____________________, the axis/center plane interpretation is used.
