GD&T Material Condition Modifiers 2

Question 1

A shaft has a true position tolerance of 0.2 MMC. At MMC the shaft diameter is 20.0 mm. If the shaft is produced at 19.8 mm, what is the total allowable position tolerance?

Accepted Answer

0.4 mm

Answer

0.2 mm

Answer

0.6 mm

Answer

0.8 mm

Question 2

Which material condition modifier requires the tolerance zone to remain fixed regardless of the feature's actual size?

Accepted Answer

RFS

Answer

MMC

Answer

LMC

Answer

Free State

Question 3

On an internal feature (hole), the LMC condition corresponds to which of the following?

Accepted Answer

Smallest allowable hole diameter

Answer

Largest allowable hole diameter

Answer

Virtual condition boundary

Answer

Midpoint of the tolerance range

Question 4

The virtual condition of an external feature controlled at MMC is calculated as:

Accepted Answer

MMC size plus the geometric tolerance

Answer

MMC size minus the geometric tolerance

Answer

LMC size plus the geometric tolerance

Answer

LMC size minus the geometric tolerance

Question 5

Accepted Answer

MMC on a datum reference

Answer

Free State (F)

Answer

RFS

Answer

Statistical Tolerance

Question 6
