23
Q

what is found in the first compartment of a feature control frame.

A

Geometric Characteristic

24
Q

what is used to cualify a primary datum

A

flatness.

25
Q

The establishment of a datum reference frame on a part:

A

Determines location of the origin on the part.

26
Q

sequence to applying Geometric Tolerancing

A

Establish and qualify a DRF, qualify the features to the DRF, and relate the features to the DRF.

27
Q

Title block tolerances ever apply to _____ dimensions.

A

Basic

28
Q

A ______ modifier is typically used for press fit applications.

A

RFS

29
Q

A _____ modifier is typically used for minimum wall thickness applications.

A

LMC

30
Q

A _____ modifier is typically used for clearance applications.

A

MMC

31
Q

Allowance is defined as the difference between _____ of mating parts.

A

MMC

32
Q

Define rule #1

A

Defines the size and form limits for regular features.
It requires perfect form at MMC.
No relations between features.

33
Q

what is the method of determining primary, secondary, and tertiary datums?

A

Largest mating surface.

34
Q

based on your knowledge so far, what are the 2 strongest characteristics symbols we can use?

A

position and profile of a surface.

35
Q

what is virtual size

A

virtual size is the largest pin that can fit into the worst case hole.

36
Q

how do you calculate virtual size of a hole at MMC?

A

take the MMC of a hole and subtract the position tolerance from it.

37
Q

The datum feature is?

A

The part itself.

38
Q

datum feature simulator

A

The measuring tool used to measure the datum, like a plate

39
Q

RMB means?

A

Regardless of material boundary.

40
Q

when pointing to a diameter where is the datum.

A

the datum is the axis.

41
Q

when a datum is qualified in line with a dimension, where is the datum.

A

the datum is the center plane of the feature.

42
Q

what happens when a hole pattern is a datum.

A

two planes are created and a cmm or special fixture is required to inspect.

43
Q

How many translations and rotations does a plane constrain.

A

One translation and two rotations.
