What is a maximum material condition?

Maximum Material Condition (MMC) and Least Material Condition (LMC): Simple Definitions. MMC is the condition of a feature which contains the maximum amount of material, that is, the smallest hole or largest pin, within the stated limits of size.

What is maximum material condition in GD & T?

In GD, maximum material condition (MMC) refers to a feature-of-size that contains the greatest amount of material, yet remains within its tolerance zone. Some examples of MMC include: Largest pin diameter. Smallest hole size.

What is maximum and minimum metal condition?

Maximum material condition (MMC) is used to indicate tolerance for mating parts such as a shaft and its housing. Least material condition (LMC) is used to indicate the strength of holes near edges as well as the thickness of pipes.

What is maximum material limit of shaft?

maximum diameter
Maximum material limit of shaft is maximum diameter of shaft. Explanation: Minimum material limit of hole is largest diameter of hole. Maximum material limit of hole is smallest diameter of hole.

What is minimum material condition?

Definition: Least material condition is a feature of size symbol that describes a dimensional or size condition where the least amount of material (volume/size) exists within its dimensional tolerance. The callout also overrides GD Rule#2 or the Regardless of Feature Size rule.

What are the 3 types of tolerances?

These are grouped into form tolerance, orientation tolerance, location tolerance, and run-out tolerance, which can be used to indicate all shapes.

What is MMC true position?

material conditions
True Position using material conditions (MMC/LMC) True position with a feature of size can control the location, orientation and the size of the feature all at once. MMC true position is helpful for creating functional gauges that can be used to quickly insert into the part see if everything is within spec.

What is maximum size limit?

8. Maximum Limit of Size: The term maximum limit of size referred to the maximum or greatest permissible size of a feature.

What is a limit dimension?

LIMIT DIMENSION : The Lower and Upper permitted sizes for a single feature dimension. 0.500-0.506 inch where 0.500 inch is the lower limit and 0.506 inch upper limit dimensions. TOLERANCE :Tolerance is the allowable variation for any given size in order to achieve a proper function.

Under what conditions is Rule #1 not applicable?

Rule #1 does not apply to a FOS on a part subject to free-state variation in the unrestrained condition. In simple terms, Rule #1 does not apply to flexible parts that are not restrained.

What are material tolerances?

Dimensional Tolerances are an accepted range of values that a shape’s specified dimension(s) is allowed to deviate between. These specifications are typically set by either ASTM International or the manufacturer of the material.

What is the maximum material condition (MMC)?

The maximum material condition is the feature of the size where it can be called out for a hole or a shaft (If it is Hole based system, MMC callout will be on Shaft if necessary, or vice versa) Maximum Material Condition (MMC) It refers to a feature of size.

What is the difference between maximum material condition and least material condition?

In GD, maximum material condition (MMC) refers to a feature-of-size that contains the greatest amount of material, yet remains within its tolerance zone. Some examples of MMC include: In contrast, least material condition (LMC) refers to a feature of size containing the least amount of material, yet remains within its tolerance zone:

What is the maximum material condition for hole dimensioning?

In Design of any machine elements, it is necessary to follow the Geometric dimensioning and tolerancing for the Holes or shafts. The maximum material condition is the feature of the size where it can be called out for a hole or a shaft (If it is Hole based system, MMC callout will be on Shaft if necessary, or vice versa)

What does MMC mean in dimensioning?

Maximum Material Condition (MMC) This is a condition where there exists a maximum amount of material within the given dimension tolerance zone. Maximum Material Condition is one side of the dimensional limits on a part. The other side of the tolerance range would be the Least Material Condition.
